You measure a brick of nickel and find it has a depth of 75.0 cm and a width of 75.0 cm. The distance from the stationary bottom and the top of the block (i.e. the height) is 91.0 cm. A shearing force, is brought to bear along the top of the brick of nickel. A shear strain of 0.00220 is experienced by the block. Nickel has a shear modulus of 3.02 x 1010 N/m2. How far did the top of the nickel brick move, relative to the bottom?

Solid Mechanics

Engineering mechanics is a branch of science that deals with forces causing bulk motion in bodies and the effect that these forces cause on the bodies. Engineering mechanics does not deal with the internal changes that occur on account of these external forces. The internal effects in a body or a material under the action of external forces are studied in a new branch of science called solid mechanics, the strength of materials, or the mechanical behavior of engineering materials.
