Answer Posted / balachandran
As the bar is subjected to unequal loading at the ends ,bar will pull aside and acceleration will be towards the net force acting ( 2P - P = p),effect p is acting on one side due to that the bar is accelerating another p is resisting the acceleration,so stress is resisting force by area of cross section,answer is P/A
