Q

Third class lever system

A 
Effort is in the middle 
Every other joint except- elbow extension and ankle plantar flexion

Mechanical advantage

A

Effort arm / load-resistance arm

18
Q

Effort arm

A

Distance from the effort to the fulcrum

19
Q

Load/resistance arm

A

Distance from load to fulcrum

20
Q
