For the frame below, please answer the following questions $($all members are A$-36$ steel$).$ Take ${}_{\text{a}\text{l}\text{l}\text{o}\text{w}}=9$MPa and ${}_{\text{a}\text{l}\text{l}\text{o}\text{w}}=0\mathrm{.}6$MPa. Neglect the weight of all members. The connection at $B$ is a pinned connection. If you need any additional information, make assumptions, but make sure to include your assumptions in your final report and your presentation.

Determine all reactions. Note that for member $AB,$ joint $A$ is fixed while joint $B$ is pinned. For member $BCD,B$ is pinned and $D$ is a roller support.

Determine the internal forces for all members. Draw the axial, shear and moment diagrams for each member.
