Given a unit cube subjected to hydrostatic pressure, P, answer the following questions. Use the material properties that you need. You must concisely explain what you are doing, as well as your assumptions.(a)Determine the state of stress (all the stresses) of the cube. Draw the stresses on the cube. (b)Determine the state of strain of the cube.(c)Determine the new volume of the cube under the hydrostatic pressure. (d)Assume now that in the middle of the cube, there is a vertical cylindrical extrusion of 0.2 diameter from top to bottom. Under this new circumstance, answer the question(c)above
