(All classes)lever- ma=d1/d2.mechanical advantage=Distance 1(between input and fulcrum) / distance 2 (between output and fulcrum)

Wheel and axle- ma=Rw/ra.ma=Wheel radius/ axle radius

Pulley-ma=2n.ma=2*Number of notable pulleys.

Wedge-ma=1/d.ma=1/depth

Screw-ma=3.14*d/L.ma=pi*diameter of screw/ lead of screw thread
