Que: Suppose a steel bar of cross sectional area A is subjected to load P at one end and 2P at the other end ,what will be the induced
Ans: Internal stress induced, as we knw stress= force/area, in that case area remain same for both end of rod but force P and 2P are apply but resultant force is only P because resultant force= 2P-P= P, so induced stress = P/A which is either compressive or tensile bcs nature of load are not clearly defined in que.
