Two parallel and opposite forces, each of magnitude `4000 N`, are applied tangentially to the upper and lower faces of a cubical metal block `25 cm` on a side. Find the angle of shear and the displacement of the upper surface relative to the lower surface. The shear modulus for the metal is `80 GPa`.
