distance from fulcrum to point of effort is de
distance from fulcrum to point of resistance is dr
Force applied is called the effort, Fe
The weight of the object to resistance, Fr
Ignoring the weight of the lever itself ... IDEALLY
Fede = Frdr
Effort ---- fulcrum ---- resistance (not necessarily equal lengths)
In this illustration, effort pushes down on left, resistance is lifted up on right.
