Question: A 5 c m 5 c m 5 c m cube of steel elastic modulus = 2 0 7 GPa, Poisson's ratio = 0 .

A 5cm5cm5cm cube of steel elastic modulus =207GPa, Poisson's ratio =0.30 is dropped off a ship into the ocean.
a. If only elastic deformation occurs in the cube due to the hydrostatic water pressure, what will the dimensions be when the cube reaches a depth of 2000 meters? Neglect edge effects - i.e., assume that the cube remains cubic. Note the water pressure is approximately equal to:
P=gh
where is the density of water
A 5 c m 5 c m 5 c m cube of steel elastic modulus
