The brake pads for a bicycle tire are made of rubber. If a frictional force of 50 N is applied to each side of the tires, determine the average shear strain in the rubber. Each pad has cross-sectional dimensions of 20 mm and 50 mm. Gr = 0.20 MPa.

Problem 3-29The brake pads for a bicycle tire are made of rubber. If a frictional force of 50 N isapplied to each side of the tires, determine the average shear strain in the rubber.Each pad has cross-sectional dimensions of 20 mm and 50 mm. Gr = 0.20 MPa. Step-by-step solution Step 1 of 2 Calculate the average shear stress: V = A Here, V is shear force acting on the brake pads. 3 Substitute 50 x 10 N for N 50 = 0.02 x 0.05 = 50 x 10 N/m 2 = 50 kPa
