A vibrationisolation unit consists of two blocks of hard rubber with a modulus of rigidity G=9MPa bonded to a plate AB and to rigid supports as shown. Denoting by P themagnitude of the force applied to the plate and by δ the corresponding deflection, determine the effective spring constant, k=p/δ, of the system.
Problem 4 Two blocks of rubber each having a height h=300 mm, width w = 400 mm, and thickness a = 50 mm are used to make a shear spring as shown. The rubber has a shear modulus G = 2.5 MPa. A load P = 30 kN is applied. a) Determine the average shear stress in the rubber pads. b) Determine the average shear strain in the rubber pads. c) What is the relative displacement 8?
