MECHANICAL ENGINEERING JOB INTERVIEW QUESTIONS:- 1.)What is Strain energy? Ans.: Strain energy is the energy stored in a body when strained within elastic limits. 2.)What is the difference between Stress and Pressure? Ans.: Pressure=Force/Area. And Stress=Resistive force/Area. Pressure represent intensity of external forces acting at a point. But stress represent intensity of internal resisting forces develop at a point. 3.)What is Truss? Ans.: Truss is a rigid structure composed of number of straight members pin jointed to each other. It can sustain dynamic and static load without any relative motion to each other. 4.)What is Poisson’s ratio? Ans.: Poisson’s ratio is the ratio of lateral strain to longitudinal strain. Its value is always less than one. Poisson ratio is often represented by 1/m or μ.
