Q-2 Two blocks of rubber, each 80 mm long by 40 mm wide by 20 mm thick, are bonded to a rigid support mount and to a movable plate. When a force P = 2,800 N is applied to the assembly, plate (1) deflects 8 mm horizontally. Determine the shear modulus G of the rubber used for the blocks. [Hint: Consider a free-body diagram of movable plate (1), where each rubber block provides a shear force that opposes the applied load P. (ii) Next, consider a free-body diagram of the upper rubber block in its deflected position.]
