classifications of beams according to theirsupport conditions:

Beams can be classified according to their support conditions in the following ways:

1. Simply Supported Beam: This type of beam is supported at both ends. One end is pinned support while the other end is a roller support. It has a tendency to bend under load.

2. Fixed Beam: This type of beam is fixed at both ends. It is more rigid and has less deflection compared to a simply supported beam.

3. Cantilever Beam: This type of beam is supported at one end and free at the other end. The free end can carry a load, and the beam tends to bend in a direction perpendicular to its length.

4. Overhanging Beam: This type of beam extends beyond its support on one or both ends.

5. Continuous Beam: This type of beam extends over more than two supports.

6. Propped Cantilever Beam: This type of beam is a cantilever beam but with an additional support somewhere along its length.

These classifications are based on the type of support and the load conditions that the beam can handle.
