A motor’s shaft is spinning at a speed of 3000 r/min. What is the shaft speed in radians per second?
A flywheel with a moment of inertia of 2 kg ⋅m^2 is initially at rest. If a torque of 5 N ⋅m counterclockwise is suddenly applied to the flywheel, what will be the speed of the flywheel after 5 s?
A motor is supplying 60 N ⋅m of torque to its load. If the motor’s shaft is turning at 1800 r/min, what is the mechanical power supplied to the load in watts? In horsepower?
If you have mechanical power in watts is 11,310 w. what will be power in horsepower?
