Question
![Two rectangular blocks of rubber, each 80 mm wide by 20 mm tall by 40 mm thick
(dimension into page), are bonded to fixed supports and to a movable plate (1), as shown in
Figure 5. When a force of P = 2,800 N is applied to the assembly, plate (1) deflects by 8 mm
horizontally to the left. Determine:
a) The force applied to each rubber block
Hint: Draw a FBD of the assembly with the fixed supports removed. ASsume that the
supports only exert horizontal force reactions.
b) The shear stress in the rubber
c) The shear strain in the rubber
d) The shear modulus G of the rubber used for the blocks
