Abeam is said to be statically determinate if all of its unknown reaction components can be determined by the static equilibrium equations. in the light of this definition, which of the following types of beam is not statically determinate? o simply supported beam aka simple beam o overhanging beam o cantilever beam o propped cantilever beam o none of the above

The correct option is propped cantilever beam.

Explanation:

A propped cantilever beam along with all the reactions is shown in the attached figure.

Since we can see that the number of unknowns are 4 but the equations of statics are only 3 thus we conclude that the beam is indeterminate to 1 degree.

For all the other beams the reactions and the equations are 3 each thus making the system determinate.
