Two rods and one cable are attached to the supports at O. If two of the forces are as shown, determine the magnitude F and direction ? of the third force so that the resultant of the three forces is vertically downward with a magnitude of 1220 lb.

 

i need answer now ty!

Two rods and one cable are attached to the supports at \( O \). If two of the forces are as shown, determine the magnitude \( F \) and direction \( \theta \) of the third force so that the resultant of the three forces is vertically downward with a magnitude of \( 1220 \mathrm{lb} \). Answers: \[ \begin{array}{l} F= \\ \theta= \end{array} \] \[ \text { Ib } \]
