Ashear spring is made from two blocks of rubber, each having a height h, width b, and thickness a. the blocks are bonded to three plates as shown. if the plates are rigid and the shear modulus of' the rubber is g, determine the displacement of plate a if a vertical load p is applied to this plate. assume that the displacement is small so that delta = a tan gamma a gamma.

Aseries piping system conveys methyl alcohol. the system consists of 70 m of 1- nominal pipe follow by 50 m of 2-nominal pipe, both schedule 40 commercial steel. the 1-nominal pipe contains 3 90° elbows (regular) anda fully open gate valve, all threaded. the pressure drop through the system is 150 kpa. determine the volume flow rate through the system that is horizontally laid.
