Question
Form the figure shown, a flexible belt placed
around a rotating drum of 4-inch radius
acts as a brake when the arm ABCD is pulled
down by the force P. The coefficient
of kinetic friction between the belt and the
drum is 0.7. What force P that
●
would result in a braking torque of 400 lb • in.,
assuming that the drum is rotating
counterclockwise. Neglect the weight of the
brake arm.
