##### Description:

At the end of this lesson, students should be able to define and calculate torque, and use it in real world applications.

Torque is a twist or a force applied off center to an object that causes a rotation. Torque is a vector that is found by using the formula  . Where F is the applied force and d is the displacement from the axis of rotation. Since torque is a vector the direction is important. For maximum torque F and d should be at 90°. Taking in the direction in to account the torque formula becomes . Where  is the angle in between F and d. Positive torque rotates counter clockwise and negative torque rotates clockwise. In the real word a positive torque will loosen a bolt and negative torque will tighten a bolt.
