Current Attempt in Progress

Turnbuckle $\backslash ($ T$\_\{1\}\backslash )$ is tightened to a tension of $150$ lb and turnbuckle $\backslash ($ T$\_\{2\}\backslash )$ is tightened to $79$ lb $.$ Determine the components of the corresponding force and moment reactions at the built$-$in support at $\backslash ($ O $\backslash ).$ Neglect the weight of the structure.
