subjected to frictional forces at belts and surfaces. When engineers design belt drives and band brakes, they engineer them to withstand the frictional forces that develop between the belts or bands and their contacting surfaces. These frictional forces lead to tensions on each side of the contacting surfaces that are unequal; the segment aligning with the motion of the belt or band has a greater tension. Blocks A and B have a masses of 190 kg and 250 kg, respectively. (Figure 2) The coefficient of static friction between A and B and between B and C is 0.200. The coefficient of static friction between the rope and peg E is 0.400. Pulley D rotates freely, and P = 23.0 N. If 0 = 60.0 degrees, what is the smallest magnitude, T, of tension, T, that causes block B to move?
