Using the following dimensions for the short-shoe drum brake shown below: radius of drum = 5 in.. shoe width = 2 in.. shoe length = 4 in., c = 10 in.. b = 6 in., a = 1.5 in., pmax = 100 psi. and f = 0.3. For maximum braking, determine:
a. The value of the actuating force, F.
b. The value of the brake torque, T.
c. The resultant force at point A.
