Steel is very stiff, and the young's modulus for steel is unusually large, 2.0×1011 n/m2. a cube of steel 25 cm on a side supports a load of 85 kg that has the same horizontal cross section as the steel cube. what is the magnitude of the "normal" force that the steel cube exerts on the load? by how much does the steel cube compress, due to the load that it supports? (give your answer as a positive number.)
