Four small rubber pads, two on each side of the crate, connect the crate to its surroundings. The pads are 10 mm thick, have planar dimensions of 40 mm and 60 mm and centers separated by 400 mm. (a) If the crate weighs 200 N (gravity acts along the y-axis), determine the shear stress in each of the four pads. (b) The crate pivots about the x-axis by 0.3°. Determine the average shear strain in each pad. (Approximate the displacement using the center of each pad.)

3. It is often necessary to isolate the vibrations of a truck
from delicate goods that it carries. A schematic of one such
vibration isolation configuration is shown. Four small
rubber pads, two on each side of the crate, connect the crate
to its surroundings. The pads are 10 mm thick, have planar
dimensions of 40 mm and 60 mm and centers separated by
400 mm.
(a) If the crate weighs 200 N (gravity acts along the y-axis),
determine the shear stress in each of the four pads.
(b) The crate pivots about the x-axis by 0.3°. Determine the
average shear strain in each pad. (Approximate the
displacement using the center of each pad.)
