The fixed end moment of a uniform beam of span $$l$$ fixed at the ends, subjected to a central point load $$P$$ is

When a column is fixed at both ends corresponding to Euler's criterion load is

A cantilever beam of span $$l$$ subjected to a uniformly distributed load $$'w'$$ per unit length resting on a rigid prop at the tip of cantilever. The magnitude of the reaction of at the prop is

For a given shear force across a symmetrical $${\rm I}$$-section, the intensity of shear is maximum at
