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?
