Key learning points
- Sporting examples of a first class lever include the neck when heading the ball in football.

Keywords
First class lever - fulcrum is placed in the middle bewteen the load and effort
Second class lever - load is placed in the middle bewteen the fulcrum and effort
Third class lever - effort is placed in the middle between the load and effort
Mechanical disadvantage - 3rd class levers cannot lift as heavy loads with the same amount of effort as 2nd class levers due to the position of the effort and load from the fulcrum
Common misconception
The effort in a lever starts in the belly of the muscle.
The effort from a muscle will start from the muscle insertion. The insertion is the tendon attached to the bone which that muscle moves.
