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. The impact load P that falls from a height of 200 mm above the collar.arrow_forwardA tank having a volume of 0.85 m3 initially contains water at 260 oF and x = 0.7. Saturated vapor is slowly withdrawn at the top of the tank as energy is transferred by heat to maintain constant pressure. The process continues until the tank is filled with just saturated vapor. Determine the heat transferred in kJ. Show all your calculations.arrow_forward
