A pivot or axle is a part of a machine that turns around a fixed point. It allows for rotational movement of components such as wheels or gears.
A rotation turns a shape through an angle around a fixed point usually on the Cartesian plane
A rotation is the type of transformation that turns a figure around a fixed point, known as the center of rotation. During a rotation, every point of the figure moves in a circular path around this fixed point by a specified angle. The distance from the center to any point on the figure remains constant throughout the transformation.
The fixed point that a lever pivots around is called a fulcrum. It is the point where the lever rotates or turns when a force is applied to one end of the lever.
That's known as a lever.
A rotation turns a shape through an angle about a fixed point
A lever.
Could be a disc brake rotor, pulley.
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 is a stiff structure that rotates around a fixed point. The fixed point around which a lever rotates is fulcrum.
