A pin$-$jointed two$-$dimensional frame structure $($truss$)$ is shown in Figure Q$1.$ The joint A is pinned with both horizontal and vertical reaction forces, while the joint E has only one vertical reaction force. External forces are applied at the joints B$,$ C$,$ D and F whose magnitude and directions are shown in the figure. The required dimensions of the structure are provided in the figure.$($i$)$ Determine the reaction forces at the joints A and E $.$

$($ii$)$ Determine the forces in each of the members of the pin$-$jointed truss using the Method of Joints.
