Question: A joint between two concrete slabs A and B is filled with a flexible epoxy that bonds securely to the concrete (see figure). The height

A joint between two concrete slabs A and B is filled with a flexible epoxy that bonds securely to the concrete (see figure). The height of the joint is h = 4.0 in., its length is L = 40 in., and its thickness is t = 0.5 in. Under the action of shear forces V, the slabs displace vertically through the distance d = 0.002 in. relative to each other.
(a) What is the average shear strain Ï„aver in the epoxy?
(b) What is the magnitude of the forces V if the shear modulus of elasticity G for the epoxy is 140 ksi?
