Do You Know: Interview Tips For Freshers Question 14:What is representative elementary volume? Answer: Smallest volume over which measurements can be made that will yield a representative of the whole. Question 15:Why are LNG pipes curved? Answer: LNG pipes are curved because LNG is condensed gas (-164 deg cel) so it can expand the pipes that is what engineers designed the LNG pipes are curve type. Question 16: What causes white smoke in two stroke locomotive engines? Answer: That is the engine running too lean (lack of fuel). This condition will lead to overheating and failure of the engine. Question 17:What does Green field project mean? Answer:
Question 18:What is the mechanical advantage of a double pulley? Answer: It only takes half the effort to move an object but twice the distance. Question 19:What is a Newtonian fluid? Answer:
Question 20:What are the points in the stress strain curve for steel? Answer: Proportional limit, elastic limit or yield point, ultimate stress and stress at failure. Read Also: Best Interview Tips Question 21: What should be done to prevent a safety valve to stick to its seat ? Answer: Safety valve should be blown off periodically so that no corrosion can take place on valve and valve seat. Question 22: Why large boilers are water tube type ? Answer: Water tube boilers raise steam fast because of large heat transfer area and positive water circulation. Thus they respond faster to fluctuations in demand. Further single tube failure does not lead to catastrophy. Question 23:What type of boiler does not need a steam drum ? Answer: Super-critical pressure boiler. Question 24:Why manholes in vessels are usually elliptical in shape ? Answer: Elliptical shape has minimum area of opening and thus plate is weakened the least. Further it is very convenient to insert and take out the cover plate from elliptical opening. Question 25: Low water in boiler drum is unsafe because it may result in overheating of water tubes in furnace. Why it is unsafe to have high water condition in boiler drum ? Answer: High drum level does not allow steam separation to be effective and some water can be carried over with steam which is not desirable for steam turbine. Work of Mechanical Engineer:All the Mechanical engineers examine, design, develop, build, and also test a mechanical as well thermal device that includes tools, engines, and machines. Generally, Mechanical engineers do the work which is given below here.

Mechanical Engineering Interview Questions for ExperiencedThe following are samples of questions that are asked to candidates with experience for a Mechanical Engineering job. 1.Can you differentiate between thermodynamics and heat transfer? Ans: Thermodynamics changes one equilibrium state to another. Heat transfer is a non-equilibrium process. 2. Why is Nitrogen used in welding? Ans: Nitrogen is used in welding to stop oxygen and air from entering the fused metal while welding. 3. Which gases can be used in welding instead of nitrogen? Ans: Nitrogen can be replaced with argon, helium and carbon dioxide. 4. Why does white smoke come out in two-stroke locomotive engines? Ans: White smoke comes out of two-stroke locomotive engines when the engine is running out of fuel. 5. What is a turboprop engine? Ans: A turboprop engine is a gas turbine engine used to power propellers. It is an efficient engine for aircraft designs. 6. How do you differentiate between a rocket motion and a projectile motion? Ans: A rocket motion uses a rocket that can accelerate the motion and resist forces like gravity. A projectile motion is a force given to a body during its launch. 7. What do you mean by orthographic drawing? Ans: An orthographic drawing is a 3D representation of any object. The 3 Faces are: Plan view, Front view and Side view. 8. Can you provide us with some examples of mechanisms from our day-to-day life? Ans: Some instances that show the use of mechanisms in our daily lives are switching a light on or winding up a clock. 9. Can you expand ABFC? Ans: The full form of ABFC is Atmospheric Fluidized Bed Combustion. 10. Can you tell the features used to identify mild steel, cast iron and high carbon steel? Ans: While mild steel gives medium and dense sparks, cast iron gives out thick and short flashes. Meanwhile, high carbon steel gives long and thick sparks. 11. Do you know why a biological shield is used in nuclear plants? Ans: The biological shield protects one from being exposed to neutron, gamma and beta radiation. 12. Now, can you explain what a nuclear reactor is? Ans: A nuclear reactor is a plant that control, sustains and maintains the nuclear fission chain reaction, and thereby prevents exposure to radioactive radiation. 13. Why do you need to subject steel metal to heat treatment? Ans: Heat treatment gives steel metal the desired properties. 14. Do you know why most gas containers are cylindrical? Ans: Gas containers are built in a cylindrical shape to withstand high pressure. The sphere can withstand high internal gas pressure. 15. Is it possible to use motor oil in a hydraulic system? Ans: You can use motor oil in a hydraulic system but it is best to avoid it. The reason is motor oil has elements that are harmful to seals and other parts of the hydraulic system. 16. Why do aeroplanes made out of thicker paper fly for a longer distance? Ans: The reason is the thicker paper has a greater mass and potential energy. This changes into kinetic energy when it is in motion and gives the plane a larger lift. 17. What is the mechanical advantage of a double pulley? Ans: A double pulley reduces the effort by half and moves the object by double the distance. 18. How are the pneumatic and hydraulic systems similar? Ans: Both the systems use pressure to act on a particular application. The difference is that the pneumatic system uses gases like air or nitrogen and the hydraulic system uses oil or water. 19. What are Newtonian fluids? Ans: Newtonian fluids are those that have a linear stress-strain relationship curve. It also passes through the origin. 20. Why do we not use galvanized pipes for steam lines? Ans: We do not use galvanized pipes for steam lines because the high pressure and temperature of the steam cause the zinc coating on the pipe to flake off. 21. What is a disadvantage of supercritical boilers? Ans: Supercritical boilers do not have a heavy drum for separating steam from the mixture of water and steam. 22. Can you explain a process flow diagram? Ans: A process flow diagram describes the primary flow course. It shows major equipment, plant streams and the relationship between components. 23. What is a universal coupling? Ans: A universal coupling is a pair of hinges connected by a cross shaft. The shaft is used to connect two shafts with axes inclined to each other. 24. What is the Otto cycle? Ans: The Otto cycle is a thermodynamic combustion cycle. It is how heat engines turn gasoline into motion. 25. What type of computer programs does a mechanical engineer use? Ans: A mechanical engineer uses software like Mathcad, MATLAB, SolidWorks and Autodesk Inventor.
