Numerical Example of Propped Cantilever:

In the above example of a propped cantilever you have seen how the method of consistent deformation can be used to solve a statically indeterminate beam problem. The method of consistent deformations is a special case of compatibility methods of solution.

You can now solve any numerical problem of propped cantilever if you remember just one formula namely the vertical reaction at the propped end VB due to a load P acting at a distance a from the fixed as given by Eq.

VB = Pa²/2L³ (3L-a)
