A $$3$$ $$m$$ long simply supported beam of uniform cross section is subjected to a uniformly distributed load of $$w = 20$$ $$kN/m$$ in the central $$1$$ $$m$$ as shown in the figure.

If the flexural rrigidity $$(EI)$$ of the beam is $$30 \times {10^6}\,\,N$$ - $${m^2},$$ the maximum slope (expressed in radians) of the deformed beam is

Consider the plane truss with load $$P$$ as shown in the figure. Let the horizontal and vertical reactions at the joint $$B$$ be $$HB$$ and $${V_B},$$ respectively and $${V_C}$$ be the vertical reaction at the joint $$C.$$

Which one of the following sets gives the correct values of $${V_B},\,\,{H_B}$$ and $${V_C}$$?

A plane truss with applied loads is shown in the figure.

The members which do not carry any force are

A propped cantilever of span $$L$$ carries a vertical concentrated load at the mid-span. If the plastic moment capacity of the section is $${M_P}$$, the magnitude of the collapse load is
