Take wmax

$=25$ kN$/$m

$.$ Assume the support reactions at A

and B

are vertical. $($Figure $1)$

Figure$1$ of $1$

A horizontal beam rests on short vertical supports at its left end $\text{'}$A$\text{'}$ and right end B$.$ Both supports are mounted on the same horizontal surface. Point C is marked on the beam $3$ meters to the right of end $\text{'}$A$\text{'}.$ Point D is marked on the beam $1\mathrm{.}5$ meters to the right of point C and $1\mathrm{.}5$ meters to the left of end B$.$ A vertical downward load of $60$ kilonewtons is applied to the beam at point D$.$ A vertically downward distributed load acts on the beam from end $\text{'}$A$\text{'}$ to point D$.$ The distributed load linearly decreases from w subscript max at end $\text{'}$A$\text{'}$ to zero at D$.$
