The three materials have equal length of 500 mm and are symmetrically rigidly fixed at the upper end while being joined by a horizontal collar (with negligible mass) at their bottom end. An application of a vertical downward load P on the assembly, results in storing a total of 20 J of energy. The moduli of elasticity for steel, brass and copper materials are ESt=200 GPa, EBr=100 GPa and ECu=80 GPa, respectively. Calculate 1. The load P if it is applied gradually.2. The load P if it is applied suddenly.3.
