A first-class lever system is one where the fulcrum is positioned between the effort and the load (resistance).
- Heading a football
- Extension at the elbow when throwing a ball
The fulcrum is positioned between the load (resistance) and the effort.
A second-class lever system is one where the load (resistance) is positioned between the fulcrum and the effort.
An example of a second-class lever system in sport is a gymnast performing a standing heel raise.
The load (resistance) is positioned between the fulcrum and the effort.
A third-class lever system is one where the effort is positioned between the fulcrum and the load (resistance).
An example of a third-class lever system in sports is a person performing a bicep curl.
The effort is positioned between the fulcrum and the load (resistance).
Levers can move large loads with a small amount of effort.
Mechanical Advantage (MA) = Effort / Load (Resistance)
Mechanical advantage is calculated by dividing the effort applied by the load (resistance).
