A beams $$PQRS$$ is $$18$$ $$m$$ long and is simply supported at points $$Q$$ and $$R$$ $$10$$ $$m$$ apart. overhangs $$PQ$$ and $$RS$$ are $$3$$ $$m$$ and $$5$$ $$m$$ respectively. A train of two point loads of $$150$$ $$kN$$ and $$100$$ $$kN$$, $$5$$ $$m$$ apart, crosses this beam from left to right with $$100$$ $$kN$$ load leading.

During the passage of the loads, the maximum and the minimum reactions at supports $$'R'$$ in $$kN,$$ are respectively

Identify, from the following, the correct value of the bending moment $${M_A}\,\,$$ (in $$kNm$$ units) at the fixed end $$A$$ in the statically determinate beam shown below (with internal hinges at $$B$$ and $$D),$$ when a uniformly distributed load of $$10$$ $$kN/m$$ is placed on the spans. (Hint: Sketching the influence line for $${M_A}\,\,$$ or applying the Principle of Virtual Displacements makes the solution easy).

A simply supported beam with an overhang is traversed by a unit concentrated moment from left to the right as shown below:

The influence line for reaction at $$B$$ is given by
