The fixed beam $$AB$$ has a span of $$3000$$ $$mm$$ and is of uniform cross-section. The plastic moment capacity $$({M_P})$$ of the beam's cross-section is $$1.5 \times {10^8}\,\,N$$-$$mm.$$

The beam will have like a simply supported beam when the magnitude of distributed load $$P$$ attains a value equal to:

A Propped cantilever beam is shown below. The plastic moment capacity of the beam is $${M_P}.$$ The collapse load is
