Question: A copper cube measures 6.00 cm on each side. The bottom face is held in place by very strong glue to a flat horizontal surface,

A copper cube measures 6.00 cm on each side. The bottom face is held in place by very strong glue to a flat horizontal surface, while a horizontal force F is applied to the upper face parallel to one of the edges. (Consult Table 11.1)
(a) Show that the glue exerts a force F on the bottom face that is equal but opposite to the force on the top face.
(b) How large m F be to cause the cube to deform by 0.250 mm?
(c) If the same experiment were performed on a lead cube of the same size as the copper one, by what distance would it deform for the same force as in part (b)?
