A stepped bar ABCD consists of three parts AB,BC and CD such that AB is 300mm long and 20mm diameter, BC is 400mm long and 30mm diameter and CD is 200 mm long and 40 mm diameter. It was observed that the stepped bar undergoes a deformation of 0.42mm when it was subjected to a compressive load of P N. Find the value of P if E=200 GPa.
