Mechanical Design Engineer Interview Questions

2,287 mechanical design engineer interview questions shared by candidates

1. Explain the difference between these two manufacturing techniques based on statistical data. How could you compare them based on average/standard deviation? 2. Explain the difference between these two products based on their stress/strain curves. How would this impact the way you use them in service? 3. You have a pipe with a blow-off valve that is meant to activate at a certain pressure. The valve consists of a spring with constant K attached to a circular disk with area A. How would you make the valve engage when the pressure exceeds that maximum allowable? 4. How would you make this capacitive accelerometer output the same voltage at a higher G level, such that the electronics system could be reused? How would you calculate the deflection of the cantilever beam assembly? 5. You have a pipe that starts at h1 and curves down to h2. At h1, there is P1 and diameter D1. At h2, you have P2 with diameter D2. How would you calculate the pressure P2 is P1 is known?
