Paragraph 1:
A lever is a simple machine, which is a long rigid object resting on a pivot or a fulcrum, which rotates. This reduces the effort that is needed to move something. In this experiment the lever is the catapults arm. The lever we have used for the throwing arm is classified as a third class lever. The base of the catapult is the fulcrum, where it pivots off. The load is the beanbag on the end of the arm and the effort is how much it takes to pull down the arm of the catapult. Tennis rackets, cricket bats, golf clubs and baseball bats are all used as third class levers. Third class levers are speed multipliers and the effort always travels a shorter distance and it must be larger than the load. A third class lever differs from second
