You are conducting a wave equation analysis of piles (weap) for a single acting ape d30-32 diesel hammer. the contractor tells you that he would like to use three (3) layers of 1/2 inch thick micarta (em = 225 ksi) and five (5) layers of 5% inch thick aluminum (eal = 11,000 ksi) as the hammer cushion. these layers have a radius of 12.5 inches as they fit into the pile driving helmet. determine the elastic modulus of the composite hammer cushion. does it affect the composite modulus if he changes the order in which he places the aluminum and micarta layers together? briefly explain why or why not.
