Support

A support is something that a beam rests upon.

Combinations
There are of course more complex combinations of these basic types:

movable hinged support
if an end of a beam is supported on a movable hinged support, it is free to rotate about the hinge and translational displacement along the plane of rolling is possible. This permits the beam to change its length

Immovable hinged support
If the ends of a beam are supported on an immovable hinged support, the ends are free to rotate, but translational displacement is not possible.
