Two 18 x 21 x 25 mm rubber mounts are used to isolate the vibrational motion of a machine from its supports. A 420-N applied load P causes the rigid upper frame (point O) to deflect 1 mm downward. Determine: (a) average shear strain in the rubber mounts, and (b) average shear stress in the rubber mounts.
