Consider a block of tofu (bean curd) in the shape of a cube. The block of tofu measures 6 cm on a side. When tofu is stretched, it stretches 1 cm per 8 cm when subjected to a force per unit area of 10N/m . If the bottom of the tofu is fixed (stationary) and the same force per unit area is applied as a shearing force, the resulting horizontal change per unit height is 1 cm per 3 cm.
(12) Evaluate Young's modulus for tofu.
Note first that the actual shape of the block of tofu is irrelevant. The moduli are characteristics of the material of the solid and not only of the specific solid. The needed values for Young's modulus, concerning the tensile strength, are given in the problem:
