only problems 1,4 and 10. show all work. (please write neatly as some tutors i can't hardly read their writing)

PROBLEMS 9.4 1. Given: T = 125 1b ft 2. Given: T = 39.4 N m w = 555 rpm W = 6.70/s P = ft 1b/s P = W 3. Given: T = 372 1b ft 4. Given: T = 650 N m w = 264 rpm W = 45.0/s P = hp P = kW 5. Given: P = 8950 W 6. Given: P = 650 W W = 4.80/s T = 540 N m T = 0 = 7. What horsepower is developed by an engine with torque 400 1b ft at 4500 rpm? 8 . What torque must be applied to develop 175 ft 1b/s of power in a motor if w = 394 rpm? 9. Find the angular velocity of a motor developing 649 W of power with torque 131 N m. 10. A high-speed industrial drill develops 0.500 hp at 1600 rpm. What torque is applied to the drill bit? 11 An engine has
