A cantilever beam is a beam supported at only one end, with the other end free to move or rotate.

• Cantilever beams are commonly used in construction and engineering for structures like balconies, bridges, and diving boards.

• The fixed end of the beam is called the 'support' while the free end is called the 'tip'.

• Cantilever beams experience bending moments and shear forces due to the load applied at the free end.

• Examples of cantilever beams include the diving board at a swimming ...read more
