Key Questions:

1. What can be used to transmit the rotational effects of a force?
   • A simple lever and a simple gear system can both be used to transmit the rotational effects of Force
2. How do levers and gears transmit the rotational effects of forces?
   • When someone uses a lever, they exert a Force (the effort) around a pivot to move an object (the load). Levers rely on the principle of moments to act as 'Force multipliers' - they reduce the effort needed to move the load by increasing the distance over which it is acting.
