fulcrum (FOOL-kruhm, FUL-kruhm)

The point on which a lever is balanced when a force is exerted.

A prop, support, or fixed point on which a lever moves, i.e. about which rotation can take place. It is the point beyond which a cantilever extends into space, its other end anchored on the opposite side of the fulcrum.

A fixed point of support of a lever which acts as the pivot about which the lever turns. In biomechanics, when viewing the movement of the skeleton, the fulcrum is a fixed point, usually a joint, on which a bony lever moves.
