| Question | Answer |
| Lever systems 1-2-3 | F-L-E Fulcrum-Load-Effort |
| Lever systems F-L-E | Fulcrum-Pivot point Load-Weight Effort-Muscular contraction |
| Lever systems 1st class lever system | Extension E-F-L or L-F-E |
| Lever systems 2nd class lever system | Plantar flexion F-L-E or E-F-L |
| Lever systems 3rd class lever system | Flexion F-E-L or L-E-F |
| Effort arm | Distance between F and E |
| Load arm | Distance between F and L |
| Mechanical advantage | Where 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 |
| Mechanical disadvantage | Where the Load arm is longer than the Effort arm. Therefore it takes more effort to produce the same amount of force |
