A beam is shown in the figure below. $($Figure $1)$

Figure$1$ of $1$

Horizontal beam $\text{'}$A$\text{'}$ B has left end $\text{'}$A$\text{'}$ supported by a roller and right end B supported by a pin. The left segment of the beam with a length of $3$ meters is unloaded. The right segment of the beam with a length of $3$ meters is subjected to a distributed vertical downward load. The value of the load increases linearly from $200$ newtons per meter at a point $3$ meters from both ends of the beam to $400$ newtons per meter at the right end B of the beam. Distance x is measured from the left end of the beam.
