Question:

A square plate of width b and thickness t is loaded by normal forces Px and Py, and by shear forces V, as shown in the figure.
These forces produce uniformly distributed stresses acting on the side faces of the place.
Calculate the change (V in the volume of the plate and the strain energy U stored in the plate if the dimensions are b = 600 mm and t = 40 mm, the plate is made of magnesium with E = 45 GPa and V = 0.35, and the forces are Px = 480 kN, Py = 180 kN, and v = 120 kN?
