- 1Lever systems 1-2-3F-L-E
Fulcrum-Load-Effort - 2Lever systems F-L-EFulcrum-Pivot point
Load-Weight
Effort-Muscular contraction - 3Lever systems 1st class lever systemExtension
E-F-L or L-F-E - 4Lever systems 2nd class lever systemPlantar flexion
F-L-E or E-F-L - 5Lever systems 3rd class lever systemFlexion
F-E-L or L-E-F - 6Effort armDistance between F and E
- 7Load armDistance between F and L
- 8Mechanical advantageWhere the Load arm shorter than the effort arm.
Therefore it takes less effort to produce a greater force.
2nd class lever= Mechanical advantage
BC effort arm is greater than the load arm - 9Mechanical disadvantageWhere the Load arm is longer than the Effort arm.
Therefore it takes more effort to produce the same amount of force
