The force transmitted through a string, rope, or cable when it is pulled tight. It acts in opposite directions on each end of the string.

Mechanical Advantage: The ratio of output force to input force in a simple machine. In the case of a light pulley, it can increase mechanical advantage by changing the direction of applied force.

Torque:

The rotational equivalent of force. In relation to a light pulley, torque refers to the turning effect produced by an applied force around its axis.
