MECHANICAL ENGINEERING JOB INTERVIEW QUESTIONS:-
1.)Explain the difference between poise and stoke.
Ans: Poise is the unit of viscosity in CGS unit and is measured in dyne sec/cm2.1 poise =10_1 Pa s.
Stoke is the unit of kinematic viscosity in CGS units and is measured in cm2/s.
2.)What do you understand by center of buoyancy ?
Ans: Center of buoyancy is the center of gravity of the displaced liquid and buoyant force acts through it.
3.)What is metacentre ?
Ans: Metacentre is the point at the intersection of the buoyancy with the vertical axis of the body.
4.)Under what condition a drill may not cut ?
Ans: When the cutting lips are not provided with clearance angles. It will cut if 12° clearance angle is ground.
