Two blocks of rubber, each 80mm long by 40mm wide by 20mm thick are bonded to a rigid support mount and to a movable plate (1). When a force of P-2800N is applied to the assembly, the rubber block above plate (1) deflects 8mm horizontally. Calculate the shear modulus G of the rubber for the blocks. Remember shear modulus is similar to Young's modulus in Hooke's law. (you come up with the formula) 8 mm 20 mm 40 mm 20 mm 80 mm
