A beam is loaded with two forces $F1=3[N]$ and $F2=7[N]$ as shown in the figure. If the geometry is given by $w1=8[m],w2=3[m],w3=7[m],w4=1[m],$ and $=10[$degree$],$ find the following using the coordinate system shown in the diagram. Note that the support at $A$ is a roller and the support at B is a pin.
