Mechanical Engineering Interview Questions and Answers
Question - 51 : - Why is tolerance analysis important for engineers?
Answer - 51 : - Analyzing tolerances helps engineers to reduce costs, avoid time-consuming iterations, and facilitate manufacturing. Every engineer optimizes tolerance as it determines how reliable the final piece will be. You can learn this by enrolling in mechanical engineering courses.
Question - 52 : - Why are galvanized pipes not used for steam lines?
Answer - 52 : - Galvanized pipes are not used for steam lines because the high temperature and pressure of the steam tend to flake off the zinc coating on the pipe. The flaked coating may clog the orifices in the event leading to an explosion.
Question - 53 : - What are the two conditions of perfect gas?
Answer - 53 : - With this question, the interviewer tries to check your analytical skills so you must consider this question while preparing for mechanical engineering interview questions and answers. You can respond to this question by saying: A perfect gas should satisfy the equation of state. And the specific heat of the gas should remain constant.
Question - 54 : - What are Newtonian fluids?
Answer - 54 : - Fluids that possess a linear stress-strain relationship curve and passes through the origin are called Newtonian fluids. Such fluids do not change due to the action of forces upon them. Learn more about this by enrolling in mechanical engineering courses.
Question - 55 : - Give some examples of mechanisms in daily life.
Answer - 55 : - You should also consider this question while preparing for mechanical engineering interview questions and answers. You can say some common examples of mechanisms are a light switch and the working of a clock.
Question - 56 : - What is extrusion?
Answer - 56 : -
Extrusion is the process of elongating a metal bar by pulling it through a mandrel. This process gives shape to the metal bar. You can learn more about extrusion through mechanical engineering certification courses.
Question - 57 : - What is F.O.F in piping design?
Answer - 57 : -
This is also an important question to be included in your mechanical project engineer interview questions and answers list. FOF means Face of Flange. It is used to determine the exact dimensions of the flange to avoid errors in measurement in the case of a vertical or horizontal pipeline.
Question - 58 : - What is an Orthographic drawing?
Answer - 58 : - It is a 3D representation of any object. These drawings are made in such a way that if the page is folded accordingly, it would create 3 faces of the shape. The 3 faces include its plan view, front view, and its side view. You can learn this through mechanical engineering courses.
Question - 59 : - Does stress produce strain or strain that produces stress?
Answer - 59 : -
It is a force that produces both of them. A strain is the measurement of the displacement of an object caused due to applied force whereas stress is the force per unit area. Hence, both are produced by the applied force.
Question - 60 : - Can we see the pipes behind the wall?
Answer - 60 : -
Through this question, the interview trees to check your general knowledge. So this is also an important question you should consider while preparing for mechanical engineering interview questions and answers. You can say yes, we can do this by using radio waves.
