(a) A 100 MPa force is applied to the surface of a material (surface area, 1 m2 ) that exerts a shear across the material (Fig. 10.4). The sample has a thickness of 10 cm and causes the surface to be displaced by 0.1 cm. What is the shear modulus of the material? (b) What is the bulk modulus of a material if a 100 MPa increase in pressure causes a 1% reduction in its volume? |
