In the theory of plastic bending of beams, the ratio of plastic moment to yield moment is called

The shape of the cross-section, which has the largest shape factor, is

For a fixed beam with span $$L,$$ having plastic moment capacity of $${{M_p}}$$, the ultimate central concentrated load will be

If $$'YY'$$ is the centroidal axis of a $$T$$-beam section, subjected to plastic moment, $${M_P},$$ the neutral axis lies
