Normally they are looking for the subject in which their company is based on. Do not worry if you tell other than the subject of company. Be true to yourself. You will be trained once you will be recruited. What was your project during Mechanical engineering? They will looking for leadership.

If you did project in group work, they will find out your leadership quality by related question. What safety precautions should be observed while working in the workshop? Keep shop floor clean, free from oil and other slippery materials. Wear proper dress and avoid loose clothing and loose hair.

Wear shoes and avoid chapels. Avoid playing, loose talk and funning inside the shop floor. Keep good housekeeping and put all unnecessary items and rejected items in scrap box. Learn everything about the machine before starting and clear all the doubts.

MECHANICAL ENGINEERING IMPORTANT MCQ PDF

Keep a safe distance from rotating and sliding parts. Never store inflammable materials inside or around the shop.

Never play with electricity, fire, parts with sharp edge etc. Keep fire buckets and extinguishers ready for use.

What are the precautions to be taken to avoid fire? The buckets along with sand should be placed inside the workshop. Switches and other electrical parts must be made of fireproof material.

Carbon dioxide gas should be place at required points in special containers. Fire extinguishers of suitable type should be placed at accessible places. What do you mean by First Aid?

First Aid is immediate and temporary care given to a person who affected accidental injury or a sudden illness before the arrival of doctor.

What is a Drawing? It is a graphical representation of a real thing to define and specify the shape and size of a particular object by means of lines.

What is Engineering Drawing? A drawing which is worked out an engineer for the engineering purpose is known as Engineering Drawing. Explain briefly the following lines used in Engineering drawing? These are terminated with arrowheads. Difference between 'Thermodynamics and Heat Transfer'? Thermodynamics mainly deals with the transfer of energy in form of heat or work between systems and surroundings with other systems in form of either heat or work in equilibrium conditions.

When there is change in one state, which was in equilibrium state and starting to change in other equilibrium state, this information helps to determine heat or work interactions due to this process. While Heat transfer deals with non equilibrium heat exchange or transfer due to temperature gradient while in thermodynamics, during thermal equilibrium No temperature gradient no heat exchange is possible. Explain in an orderly manner how the force in the member of a truss be detected using the method of joint.

The steps required to calculate the force are as follows: The reaction at the support has to be first calculated. Once the reaction is calculated the direction of force of the member is made to make it tensile. On getting the result to be negative the direction assumed is wrong and this implies the force being compressive in nature. A joint needs to be selected whose 2 members are not known. The lami's theorem is used on the joint on which less than three forces are acting.

Mechanical Engineering Interview Questions & Answers

After the above process is complete the free body diagrams of the joint needs to be made. When two or more different sorts of metal come into contact in the presence of an electrolyte, a galvanic couple is set up as different metals have different electrode potentials.

The electrolyte provides a means for ion migration whereby metallic ions can move from the anode to the cathode. This leads to the anodic metal corroding more quickly than it otherwise would; the corrosion of the cathodic metal is retarded even to the point of stopping. The presence of electrolyte and a conducting path between the metals may cause corrosion where otherwise neither metal alone would have corroded. Wet Corrosion: The main feature of corrosion of a divalent metal M in an aqueous solution containing oxygen is because of the corrosion process consists of an anodic and a cathodic reaction.

The cathodic reaction in the example is reduction of oxygen. It is seen that the process makes an electrical circuit without any accumulation of charges. The electrons released by the anodic reaction are conducted through the metal to the cathodic area where they are consumed in the cathodic reaction. A necessary condition for such a corrosion process is that the environment is a conducting liquid an electrolyte that is in contact with the metal. The electrical circuit is closed by ion conduction through the electrolyte.

In accordance with the conditions, this dissolution process is called wet corrosion, and the mechanism is typically electrochemical. How Do Concrete Pumps Work? What Is Representative Elementary Volume? Smallest volume over which measurements can be made that will yield a representative of the whole.

Parallel disk gate valves use two disks with a spring in between them, sliding into the seats. At low pressure, the spring forces the disks outward against the seats, sealing off the valve. At high pressure, all the sealing is accomplished by the downstream disk. Wedge gate valves use a tapered disk that slides into two seats set at a slight, converging angle. The wedging action provides the sealing force between the disk and the seat.

Single disk gate valves are used where the flow is always one-way like sluices on dams. There is some flexibility in the attachment of the disk to the stem, so the differential pressure on the disk pushes it against the seat, sealing it off. Plastics are the general term for a wide range of synthetic or semisynthetic polymerization products. There are many different plastics; all have their own density! What Is An Ortographic Drawing?

Orthographic projections are views of a 3D object, showing 3 faces of it. The 3 drawings are aligned so that if the page were folded, it would create part of the shape.

It is also called multiview projections. The 3 faces of an object consist of its plan view, front view and side view. There are 2 types of orthographic projection, which are 1st angle projection and 3rd angle projection.

In combustion engines, there are only really two ways to increase power, firstly increase the amount of fuel in the engine either increase the displacement, or add more cylinders or increase the amount of air in the engine for a more effective explosion of the fuel Superchargers are powered by the engines crankshaft, which is connected usually by a belt drive.

By using radio waves. Ballast has several functions: It enables water to drain from the track. It assists in helping control the thermal expansion of continues welded rail. As a train passes the rails, it supports the train.

It distributes the weight of the train from the track structure to the sub grade. Maintains a smooth running surface for the train to run on. Brownish and sort of grey.

Generally nozzle is a tapered tube. It is used where high velocity and low pressure is required. It depends on the continuity equation. According to continuity equation if the flow rate is to be remained same the product of area and velocity should remain same on the inlet and outlet.

So if area decreases then the velocity increases. Polytrpoic is a thermodynamic process. It follows the relation. For same compression ratio petrol engine has greater efficiency then diesel engine.
