6. A flexible connection consisting of rubber pads (thickness t = 9 mm) bonded to steel plates is shown in the figure. The pads are 160 mm long and 80 mm wide. (a) Find the average shear strain Yavr in the rubber if the force P = 16 kN and the shear modulus for the rubber is G = 12.5 MPa. (b) Find the relative horizontal displacement & between the interior plate and the outer plates. 160 mm 221 P Rubber pad X< X 80 mm Section X-X Rubber pad t = 9 mm K t = 9 mm
