Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

Today, waterwheels are not often used to grind food. Instead, we have electrical devices such as blenders, choppers, and mixers. The electric motors in these devices are similar to a waterwheel, but instead of falling water causing the wheel to spin,electricity causes a shaft to spin. The specifications on a particular electric motor reports that at 1.75 103 rpm, it puts out5 hp. What is the corresponding torque in N m?
