Mini-Quiz: Torque is a Rotational Force

by Ron Kurtus

Take this Mini-Quiz to check your understanding of the lesson material.

1. What happens to the torque if the moment arm is increased?

The torque decreases with the length of the arm

Nothing happens since torque is independent of distance

The torque increases with the length of the arm

2. What is the torque at a bolt from a force of 5 pounds on a 1-foot wrench?

5 foot-pounds

1/5 foot-pound

0.5 foot-pounds

3. If an electric motor turns a wheel shaft with a torque of 2 N-m, what is the force at the edge of a wheel 1 meter in diameter?

2 N-m / 1 m = 2 newtons

2 N-m / 0.5 m = 4 newtons

2 N-m * 1 m = 2

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.

Consider the direction of a force in your life
