Answer all problems

Show all work $($use back side of paper if necessary$)$ to earn partial

credit points i$.$e$.$ FBD$,$ equations, sanity check, etc.

Please write neatly

Circle your final answers

Although partial credit will be awarded, score weighted towards final

correct answers. Hint: Follow the solution "process"

Problem #$1(25$ Points$)$

Consider the bridge shown below. We'll look at just one joint $($circled$)$ and

assume that all the beams are in either tension or compression. This results

in the FBD below. Find the magnitude of the unknown force. Use the

horizontal axis as your reference for the direction.
