A simply supported beam $$AB$$ has the bending moment diagram as shown in the following figure :

The beam is possibly under the action of following loads

The bending Moment diagram for a beam is given below:

The shear force at sections $$aa'$$ and $$bb'$$ respectively are of the magnitude

A three-span continuous beam has an internal hinge at $$B.$$ Section $$B$$ is at the mid-span of $$A.C.$$ Section $$E$$ is at the mid-span of $$CG$$. The $$20$$ $$kN$$ load is applied at section $$B$$ whereas $$10$$ $$kN$$ loads are applied at sections $$D$$ and $$F$$ as shown in the figure. Span $$GH$$ is subjected to uniformly distributed load of magnitude $$5$$ $$kN/m$$. For the loading shown, shear force immediate to the right of section $$E$$ is $$9.84$$ $$kN$$ upwards and the sagging moment at section $$E$$ is $$10.31$$ $$kN$$-$$m.$$

The vertical reaction at support $$H$$ is
