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.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
