## Question:

Suppose you needed to raise a 215 kg mower a distance of 6.0 cm above the ground to change a tire. If you had a 2.2-m-long lever, where would you place the fulcrum (in m) if your force was limited to 310N? (Enter the minimum distance measured from your end of the lever.)

## Torque:

Torque is a force applied across a distance, causing a form of rotation. By using a lever, the torque generated by a force can be used to lift a much heavier object, so long as the fulcrum is well placed to make the torque from the force exceed the torque by the heavy object's weight.

To solve, we will need to perform a torque balance, where the torque of the applied force is equal to the torque required to lift the lawnmower. The... Torque: Definition, Equation & Formula
