Steel is very stiff, and Young's modulus for steel is unusually large, 2 × 1011 N/m2. A cube of steel 17 cm on a side supports a load of 58 kg that has the same horizontal cross section as the steel cube.
(a) What is the magnitude of the "normal" force that the steel cube exerts on the load?

F= N


(b) What is the compression of the steel cube? That is, what is the small change in height of the steel cube due to the load it supports? Give your answer as a positive number.

|compression|= m
