rotation
That's known as a lever.
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.
An enlargement with a scale factor of 0.
