just a ****ing bar
A lever.
Fulcrum * * * * * The fulcrum is the fixed point. The bar is a lever. Admitedly, it would help if questions were asked properly.
The bar is a rigid straight finite object that is attached to one fixed point. The bar can be moved but the point where it is attached must stay where it is. In theory, therefore, the bar can be rotated around that fixed point in any direction. At the level of mathematics that your question suggests, the bar is movable in only one plane.
A lever. The fixed point is called the fulcrum.

A lever is a simple machine but it is made out of a stiff bar that moves freely around a fixed point.
