A vibration isolation unit consists of two blocks of hard rubber Problems 111
bonded to plate AB and to rigid supports as shown. For the type
and grade of rubber used tall 5 220 psi and G 5 1800 psi. Knowing
that a centric vertical force of magnitude P 5 3.2 kips must
cause a 0.1-in. vertical deflection of the plate AB, determine the
smallest allowable dimensions a and b of the block.
