MECHANICAL ENGINEERING JOB INTERVIEW QUESTIONS:-
1.)What is the difference between anti-friction and hydrostatic bearings ?
Ans.-In anti-friction bearings rolling components are introduced between the sliding surfaces. In hydro static bearings lubricant is supplied at a high pressure to a pocket in the bearing.
2.)Define primary and secondary transducers ?
Ans.- A primary transducer senses a physical phenomena and converts it to an analogous output.The analogous output is then converted into an electrical signal by secondary transducer.
3.)What is the purpose of D-slide valve in steam engines ?
Ans.-It controls the piston position for cut off of steam, for release of steam and compression position for steam in cylinder.
4.)What is meant by loading ?
Ans.-During the act of measurement the measuring instrument takes energy from the signal source or measured medium and thus the signal source is altered. This effect is called loading.
