Question:

A square plate is 1.0 × 10-2 m thick, measures 3.0 × 10-2 m on a side, and has a mass of 7.2 × 10-2 kg. The shear modulus of the material is 2.0 × 1010 N/m2. One of the square faces rests on a flat horizontal surface, and the coefficient of static friction between the plate and the surface is 0.91. A force is applied to the top of the plate, as in Figure 10.29a. Determine

(a) The maximum possible amount of shear stress,

(b) The maximum possible amount of shear strain,

(c) The maximum possible amount of shear deformation DX (Figure 10.29b) that can be created by the applied force just before the plate begins to move.
