Fluid Mechanics Experiments and Calculations

In today’s article we shall discuss about fluid mechanics citing experiment using Pascal’s law as the underneath principle.

This article discusses the concept of simple fluid mechanics experiment and its calculation used in the marine and other fields that involve hydraulics. The experiment explained is used in gear systems that run by hydraulic steering, that is employed on ships for steering it either towards starboard or a port.

This fluid mechanics experiment is based on Pascal’s law.

Experiment:

Let’s consider a fluid system that has two cylinders of varying diameters. One cylinder larger and contains a ram which moves up and down on applying pressure. Another cylinder is smaller and has a plunger which is mobile. The larger cylinder and the smaller ones are connected by a pipe of suitable thickness in order to bear the pressure created within. The cylinders and pipe has liquid or hydraulic oil through which the pressure is transmitted.

On application of a small force on the plunger in a downward direction, a pressure is created on the liquid in contact with the plunger. This pressure is equally transmitted in all the directions and acts on the larger ram to push it.

It is noticed that movement of the plunger in the small cylinder is due to the small force applied and displaces the hydraulic fluid within. As the hydraulic fluid or oil can’t be compressed inside the cylinder, pressure will be created inside the cylinder which depends upon the applied force and diameter of the plunger. The pressure created inside the cylinder will equally act in all the directions as stated by Pascal’s law. The same pressure then acts on the ram that’s in contact with the hydraulic fluid. This will apply a force on the ram to make it move in the direction corresponding to the applied force. The force moving the ram depends on the ram diameter and the produced pressure in the hydraulic fluid owing to the applied force on the plunger. Ultimately, the force applied on the plunger is transformed into the desired movement on the ram which is the yield of the system.

An experiment using Pascal’s Law:

Calculations

    • f1 = applied force on the plunger
    • f2 = force acting on the ram
    • A1= area of the plunger
    • A2= area of the ram.
    • p = intensity of pressure as a result of f1.

Hence,

Pressure intensity created by f1 = (f1) / (A1)

According to Pascal’s law, intensity of pressure in a stable fluid is equally transmitted in all directions, so the above intensity of the pressure created by the plunger will be transmitted equally in all directions. Hence the pressure intensity on the ram is equal to the applied force on plunger f1 divided by plunger-area, A1.

Pressure intensity on ram = (f2) / (A2)

Mathematically, we get

(f1 / A1) = (f2 / A2).

Total force acting on ram, f2 = (f1 × A2) / A1

Example for the above Derivation

Let a ram of 300 mm diameter has to be moved, the diameter of the plunger is 20mm, and the applied force on the plunger is 100N.

Therefore, Force available on the ram = (Force on the plunger × Area of ram) / Plunger area

Ram area = ( 3.14×0.32 ) / 4

Ram area=0.07068 mm2

Plunger area = ( 3.14 ×.022 ) / 4

Plunger area =0.00031 mm2

Available force on ram = (100 × 0.07068 ) / 0.00031

Applied force on ram =22509.55 N

It’s clear that the applied force on the system is 100N which gets converted to 22510N (approx) which could easily operate the heavy system.

Application

The above experiment is applied in hydraulic steering gear with certain special arrangements. The steering wheel movement in a navigation bridge might help to turn the rudder towards starboard or port owing to the oil pressure that is being applied on the ram.

Hydraulic Steering Gear

Working

When wheel (1) turns anti-clockwise, the pinion (2) makes the toothed rack (3) move downwards and eventually, the toothed rack (4) upward. Being fixed with the two pistons, (5) and (6) they also moves. As the two cylinders (7) & (8) are filled with oil, piston movement yields oil pressure which is applied to the bottom of the piston (10) and moves it upward and finally forces oil in upper part of cylinder (9) up in to cylinder (8).

Piston (10) has a piston rod well connected to a slide valve (11). In the mid position, the slide valve closes the ports (12), (13), (14) in the slide valve that house (15). With piston (10) moving upward, the slide valve (11) moves along and opens port (12) and (14). These causes oil to come under the side of piston (20) and is pushed into the slide valve that house (15) and out via port (12) to the discharge tank (16). Eventually, piston (21) moves upward along with piston (20). This upward movement applies force on the tiller arm which is placed just above the rudder stock and finally causes the rudder to move.

Conclusion:

The basic principle of the experiment is that pressure intensity exerted by hydraulic fluid is equally distributed in all the directions.

With this I conclude. To know more, keep visiting our website.

An Overview Into Electromechanics

Electromechanics

Mechanical engineering is one of the vast and diverse engineering subjects. Once you earn the mechanical engineering degree, you could enter a variety of different professions.

Mechanical engineering is one of the most assorted engineering subjects. Once you get your mechanical degree, you can make way into a variety of different professions. Mechanical engineers work in diverse areas from heating and air conditioning (HVAC), automotive, aviation, automation, part designing, assembly work, civil construction, to medical engineering. You can see so many disciplines fall under mechanical stream.

Fluid mechanics cover aviation, HVAC, environmental, and even medical devices. Statics and dynamics include civil construction and designing of parts. Industrial subjects like robotics, machining, and CAD applies to the world of production and automation. Mechanical engineering opens doors to several industries. So it’s undoubtedly, that the future belongs to the electromechanical engineers.

The future of engineering is based on the combination of electrical and mechanical engineering into electro mechanics. (Courtesy to Thinkstock)

The future industry is one of the advanced mechanics. The readers would at first hint could grasp the idea we are talking about…Yes, it’s the diverse of things, sensing technologies on end devices, human-machine interfaces on production machineries, robots collaborating with human workers, and artificial-intelligence or machine-learning technology in equipment like hydraulic pumps.

According to statistics, only a few industries in India have combine electrical and mechanics to make the study of electromechanical engineering a subject. The university offer courses as a direct response to the emerging demand from industrial companies for engineering graduates with a wide variety of technical knowledge. The study of the subject offers graduation knowledge and skill sets to design, manage and operate electromechanical systems, mainly systems that are automatic.

The University providing the courses, include the following classes under their degree guideline:

Some Important Mechanical Interview Questions

1. What is second law of thermodynamics?

The law states that, the entropy of the universe keeps on increasing over the time and reaches a maximum value.

2. What types of pipes used in steam lines?

Pipes made of moderate steel with welded fittings are commonly used. Galvanised pipes are never used.

3. Differentiate between shear center flexural center of twist and elastic centre?

The shear center is only a centroid of a cross-section. The flexural center is the center of twist, the point on a beam where you can add a load without torsion. The elastic center is present at the center of gravity.

4. What is ferrite?

A rock made of iron.

5. Differentiate between projectile motion and a rocket motion?

A projectile with no motor on it, gains momentum when launched.

A rocket has an inbuilt motor on it; hence it can accelerate itself while moving and can resist other forces like gravity.

6. Define cotter joint?

These joints are used to connect two rods, which are under tensile or compressive stress.

7. What is the name of an alloy of tin and lead?

This alloy is called solder.

8. What does F.O.F. stand for in piping design?

FOF is the acronym for Face of Flange. A flange has either of the two types of faces:
a) Raised face
b) Flat face
The F.O.F helps to know the accurate dimension of the flange and avoid minute errors in measurement with vertical or horizontal pipelines.

9. What is an Otto cycle?

Otto cycle shows the functioning of a four stroke engine. The cycle begins with an in stroke, after closing the in stroke; it moves to the compression stroke, and because combustion next is power stroke, heat exchange strokes where heat is unaccepted and the exhaust stroke. It was created by Nicolas Otto, a German engineer.

10. Define gear ratio?

It is ratio of a number of revolutions of the pinion gear to one revolution of the idler gear.

11. Define annealing?

A process of heating a material above the temperature of re-crystallization and then cooled after a specific duration. This enhances hardness and strength of the material.

12. Explain uniformly distributed load?

A uniformly distributed load or a UDL is a load that is spread over a beam such that, each unit length is loaded to the same extent.

13. Define enthalpy?

It is the heat content of a system.

14. Explain a positive displacement pump?

This pump enables a liquid or gas to pass by stopping a fixed amount of fluid or gas and then displacing that trapped volume into the discharge pipe. Positive displacement pumps are of two types: Rotary-type and Lobe pumps which are similar to oil pumps in car engines. These pumps provide a non-pulsating displacement unlike the reciprocating pumps. Hence, they are termed as positive displacement pumps.

15. Why to use hydraulics rather than pneumatics?

Hydraulics is helpful for forces which are higher & specific motion compared to pneumatics, because hydraulic systems mainly runs at higher pressures than that of pneumatics.

Movements are more precisely repeatable because hydraulics makes use of an incompressible liquid to transfer power, whilst pneumatics uses gases.


The advantages of pneumatic systems are that they are cheaper than hydraulic systems, could move faster and do not leak oil even on developing a leak.

16. Define isometric drawing.

A 3-D drawing used by architects, draftsmen, etc

17. Mention the advantages of gear drive.

Advantages:

It helps to get various speeds under different load conditions.

Biomechanics Definition And Application

Everybody has been to a mechanic, some time or the other. For instance, you took your car to him either for regular servicing or something happened badly. Owing to their Knowing and understanding of those machines they could likely analyze the problems and help you with your vehicle within a couple of days, at maximum.

As lesser people have been to a biomechanics or even know about them. In this article, we will discuss what exactly the field of biomechanics is about and look at its applications and utilities in this century.

Biomechanics is actually the investigation of how the structures and systems of life form, from the smallest flora to the biggest fauna, who responds to various stimuli and forces. In people, biomechanics refers to the findings and study of how the systems like skeletal and musculature, functions under various conditions. Generally, in biomechanics, researchers frequently try to apply material science and other mathematics based types of study to find the limits and capacities of bio forms.

To mention, biomechanics has been around since the questioning by Greek and Roman personalities to analyse the functioning of animals started with animals and vivisecting people to find and study their anatomy. A number of the past philosophers and researchers tried their hand at some type of biomechanics, be it Aristotle, who has written “On the Motion of Animals” during the fourth century BC, to Leonardo da Vinci, who studied in details human muscle and functioning of joints in the fifteenth century. In the nineteenth century, several Europeans were intrigued, for unknown reasons with the movement of stallions and broadly studied the biomechanics of a horse’s galloping movement.

Today, as opposed to a field where researchers and scientists immerse in, biomechanics has its own specific branch of human and life science, with departments in health care units and institution, devoted to the study of the subject.

Applications

The Biomechanics in practice is now concentrating on several clinical findings and experiments. The primary area is devoted to injury and clinical biomechanics includes study of the biomechanics of injuries to musculoskeletal system, distraction in mandible osteogenesis, or due to drilling.

Since biomechanics is the study of human movements and interaction with nature, the field has vast applications in day to day life and covers different branches of science.

Robotics, material science, mathematical findings, imaging, and computer software are some of most recent devices used in the betterment of athletic activities. Together they are used as a part of study of biomechanics, which are the physiological study forces, their interaction and effects on and within human body.

Hope the discussion was beneficial for you. We conclude.

Reasons To Study Mechanical Engineering

Mechanical Engineers have good graduate prospects!

In a very tough graduate job market it’s fair to say that degree-level engineers are doing great.  Engineers build the society and mechanical engineers apply fundamental laws of maths and physics to create and build mechanical devices that we use every day.

So there’s no surprise to see that mechanical engineer students have good graduate prospects. Statistic shows that 81% of mechanical engineers were in positive destination, six months after graduating in 2013. A positive destination signifies either professional-level employment or postgraduate study.

Great starting salaries

Professionals with mechanical engineering skills are highly valued in society and their salaries reflect that same. Again as per statistics, mechanical graduates in professional jobs receive, on average, £26,197 a year, that rises in between £40,000 and £55,000 after 10 years in job.

Mechanical Engineers are multi-skilled

A mechanical engineer is known as a jack-of-all-trades, and those in the engineering sector often does.

Accelerometers And Their Working

When you use the compass on an app on your smartphone, it knows which direction the phone is pointing. With stargazing apps, it knows where in the sky you’re looking to properly display constellations. Smartphones and other mobile technologies identify their orientation through the use of an accelerator, a small device made up of axis-based motion sensing.

The motion sensors in accelerometers could even be used to detect earthquakes, and might be used in medical devices such as bio limbs and other artificial body parts. Several devices, part of the quantified self movement, use accelerometers.

This is an electromechanical device used to measure forces of acceleration. Such forces might be static, like the continuous force of gravity or, as is the case with many mobile devices, dynamic to sense movement or vibrations.

Acceleration is the measurement of the change in velocity, or speed divided by time. For example, a car accelerating from a standstill to 60 mph in six seconds is determined to have an acceleration of 10 mph per second (60 divided by 6).

The purpose

The use of accelerometers extends to multiple disciplines, both academic and consumer-driven. For example, accelerometers in laptops protect hard drives from damage. If the laptop is to drop suddenly while in use, the accelerometer would detect the sudden free fall and immediately turn off the hard drive to avoid hitting the reading heads into the hard drive platter. Without this, the two would strike and cause scratches to the platter for extensive file and reading damage. Accelerometers are used in cars as the industry method way of detecting car crashes and deploying airbags almost instantaneously.

In another instance, a dynamic accelerometer fathoms gravitational pull to determine the angle at which a device is tilted with respect to the Earth. By sensing the quantity of acceleration, users could analyze how the device is moving.

Accelerometers allow the user to understand the surroundings of an item better. With this small device, you could determine if an object is moving uphill, whether it will fall over if it tilts any more, or whether it’s flying horizontally or angling downward. For example, smartphones rotate their display between portraits and landscapes mode based on how you tilt the phone.

Working

An accelerator looks like a simple circuit for some larger electronic device. Besides its humble appearance, the accelerometer has many different parts and works in many ways, two of them are piezoelectric effect and the capacitance sensor.

The piezo effect is the most common form of accelerometer and uses microscopic crystal structures that become stressed due to accelerative forces. These crystals develop a voltage from the stress, and the accelerometer interprets the voltage to decide the velocity and orientation.

The capacitance accelerometer sense changes in capacitance between microstructures located next to the device. If an accelerative force moves one of the structures, the capacitance would change and the accelerometer will translate that capacitance to voltage for interpretation.

Accelerometers are made up of several components, and could be purchased as a separate device. Analog and digital displays are present, though for most technology devices, these components are integrated into the main technology and reached using the operating system.

Accelerometers are made up of multiple axes, two to determine most 2D movement with the option of a third for 3D positioning. Most smart phones typically make use of three-axis models, whereas cars use a two-axis to determine the moment of impact. The sensitivity of the device is quite high as they intend to measure even very minute shifts in acceleration. The more sensitive the accelerometer, the more ease in measuring acceleration.

We conclude the discussion now.

Technology employs electronics, computers, pneumatics & hydraulics as a part of the robotics history. Robotics currently is one of the mankind’s supreme achievements and is the best endeavour of man to create an artificial being.

Robots are considered as a 20th century discovery, but their origins lies in the far history. The prehistoric age about 270BC the Greeks & Egyptians produced mechanical machines to execute easy tasks. Today, automatic toys amuse and quite more complex machineries are invented. At present, robots of several types occupy the globe and are brought into play for diverse applications.

Though the division of Robotics is new, the making of Robots started in the year 1250 when the first man-made automated human was developed.

Take a look into the history of robotics in the 20th century:

Year 1921: the Czech dramatist “Karel Capek” coins the word robot in his play Rossum’s Universal Robots (R.U.R). The word robot is derived from a Czech word that means “compulsory labor.”

Robots are not harmful to the humans.

Year 1956: George Devol and Joseph Engelberger established the first robot company.

Year 1959: computer assisted manufacturing verified at MIT.

Year 1961:UNIMATE- The first industrial robot was online in a General Motors automobile plant.

Year 1963: First computer controlled robotic arm was created and was named as Rancho Arm. The invention was made for handicapped peoples.

Different Branches Are There In The Development of Robotics:

Robotics is a multi-disciplinary domain. The different branches included in the development of Robotics are:-

Mechanical Engineering: Deals with machinery & structure of Robots.

Electrical Engineering: Deals with control & intelligence of Robots.

Computer Engineering: Deals with mobility and observation of Robots.

Classification of Robots:

Robots are categorized based upon the circuits of the Robots and the variety of applications it can perform. The robots are classified into three types:

Simple level Robots-They are automatic machines with no complex circuit. They are developed to extend human potential. For Example: Washing Machine.

Middle level Robots–They are programmed but can never be reprogrammed. They have sensor based circuit & can perform multiple tasks. For Example: Fully Automatic Washing Machine.

Complex level Robots-They are programmed and could be reprogrammed as well. They have complex model based circuit. For Example: Laptop or Computer

Types of Robotics:

Generally, a robot’s distinctiveness transforms depends on the atmosphere it works in. Some of them are as:-

  1. Outer Space – Robotic arms under the control of a human are employed to unload docking cove of outer-space shuttles to launch satellites or to build a space station.

  2. The Intelligent Home – They can scrutinize home safety, ecological situations and energy consumption. Door & windows could be unlocked mechanically and electrical device like lights and A/C can be pre-programmed to turn on.

  3. Exploration – Robots can enter environments which are injurious to human beings. E.g. observing the atmosphere within a volcano or investigating deep marine life.

  4. Military Robots – Flying robot like drones are used to keep a watch in present time’s modern armed force.

  5. Farms – They are programmed to cut and collect crops. Robotic milk farms help workers to nourish and milk their cattle from a distant.

  6. Hospitals – Designing of a robotic suit is under process that will allow nurses to raise patients without injuring their backbones.

  7. Disaster Areas –Observation robots can work in dangerous environments like urban site havocked by earthquakes and inspecting floors, walls, and roofs for structural reality.

  8. Entertainment – Interactive robots, show behaviours and education capability.

There is many more application of Robotics.

Applications:

Currently, robots do a number of different jobs in numerous fields and the amount of tasks assigned to them is rising progressively. Here robots are classified based on their application.

1. Industrial robots – They enact role in an industrialized manufacturing atmosphere. They have articulated arms mainly created for applications like painting, material handling, welding and others.

2. Domestic robots – They are used at home. They consist of numerous different gears like robotic pool cleaners, robotic vacuum cleaners, robotic sewer cleaners and other robots that can perform several household tasks.

3. Medical robots – They are employed in medicinal institutes. First of the type of and best surgical treatment robots.

4. Service robots – They could be data collecting robots, robots prepared to show technologies, robots employed for research, etc.

5. Military robots – Robots used in military & armed forces. They consist of bomb discarding robots, different shipping robots, exploration drones.

6. Entertainment robots – They are extremely of wide-ranging category. It starts with model robots like robosapien or the running photo frames and finishes with real heavy weights like articulated robot arms employed as movement simulators.

7. Space robots – They would consist of the robots employed on Canadarm that was brought into action in space Shuttles, the International Space Station, together with Mars explorers and other robots employed in exploration of space & other activities.

8. Hobby and competition robots – Robots created by students. Sumo-bots, Line followers, robots prepared for learning, fun and contests.

So you could see that there are a number of examples that fit well into one or more of these types. For illustration, there can be a deep ocean discovery robot that can collect a number of precious information that can be employed for military or armed forces purpose.

Ultrasonic Machining, Working Principles & Advantages

Ultrasonic machining is bringing new changes to the manufacturing industries with its superlative performance. The main reason why this machining process is used in the manufacturing area is because it produces less heat in the process. All the operations done with the ultrasonic machining method are cost effective and best in results. Ultrasonic machining is an abrasive process which could create any material into hard and brittle form with the help vibration and the passage of abrasive particles towards the work piece.

It is also known as a Ultrasonic impact grinding in an operation that involves a vibrating tool fluctuating the ultrasonic frequencies in order to remove the material from the work piece. The process involves abrasive slurry that runs between the tool and the work piece. Due to this, the tool and the work piece never interact with each other. The process rarely exceeds two pounds.

Ultrasonic Machine is Useful for Hard Material

This method is the best choice for dealing with hard materials like ceramic matrix composites, piezo-ceramics, Quartz, ferrite, diamonds, technical ceramics, PCD, sapphire, carbide and similar ones.  

The Process

The tool present for cutting the materials is made from a soft material in contrast to the work piece. The tool is made from materials like soft steels and nickel. When the tool vibrates, the abrasive slurry is added which contains abrasive grains and particles. The abrasive slurry is added till the work pieces interact with the grains. Due to the particles in liquid added, the work brittleness of the work piece abrades the surface as the tool deforms gradually.

Working Principle

The time spent on ultrasonic machine depends on the frequency of the vibrating tool. It also depends on the size of grains of the abrasive slurry, the rigidity and the viscosity as well. The grains used in the fluid are usually boron carbide or silicon carbide as they are rigid than others. The used abrasive could be carried away easily if the viscosity of the slurry fluid is less.

Advantages and Disadvantages

Advantages

  • Machine all types of hard materials
  • Produce finely finished and structured results
  • Produce less heat
  • Various hole cut shapes due to vibratory motion of the tool  

Disadvantages

  • Need a higher degree of integrity and skills
  • No certified record of radiography
  • The large grain size causes defects
  • Additional repairs might be needed owing to spurious signs and lack of knowledge of the process

Ultrasonic machines are the future! They are used all over the world for creating hard and brittle forms of materials for the industrial uses. A lot of operations could be performed with the ultrasonic machine which can benefit the industrialists in a variety of ways. The advanced technology create solution which helps in opening up the market opportunities and has made things easy.
