Question: When a force of P = 30 lb is applied to the brake arm, the 50-lb cylinder A is descending with a speed of 20

When a force of P = 30 lb is applied to the brake arm, the 50-lb cylinder A is descending with a speed of 20 ft/s. Determine the number of revolutions wheel B will rotate before it is brought to a stop. The coefficient of kinetic friction between the brake pad C and the wheel is μ_k = 0.5. The wheel's weight is 25 lb, and the radius of gyration about its center of mass is k = 0.6 ft. 0.375 ft- 0.75 ft B A 0.5 ft- D 1.5 ft 3

0.375 ft- 0.75 ft B A 0.5 ft- D 1.5 ft 3 ft P
