Linear motion mechanisms
A lever is a rigid bar that is used with a point of support or a fulcrum.
The load and the effort are on opposite sides
of the fulcrum.
The effect of the effort applied can be multiplied or reduced depending on where the fulcrum is in relation of the load
The load is between the effort and the fulcrum
The effect of the effort is always multiplied (d>r).
The effort o between the fulcrum and the load
The effect of the effort is always reduced (d<r)
