1. A belt is wrapped around a pulley creating a torque of 186 N-m. What power is being transmitted if the pulley is rotating at 200 rpm?
2. Knowing that 1 horsepower = 550 ft-lb/sec, what horsepower is required to raise a 100-lb weight to a height of 8 feet in 4 seconds?
3. The 300-kg block is acted upon by a force P, pulling it as shown. P makes an angle of 36o with the horizontal. If the coefficient of sliding friction between the block and the floor is 0.35, determine the force required to start moving the block. Remember:
Weight, W = (mass) X (acceleration due to gravity)
