**A.**

Equilibrium condition for torques about the pivot:

$\overline{){\mathbf{\Sigma}}{\mathbf{\tau}}{\mathbf{=}}{\mathbf{0}}}$

(4.00)T sin (θ) - (4.00)(300) - (4.00/2)(200) = 0

sin θ = 3.00/5.00

A. Find the tension in the cable (N).

B. Find the horizontal component of the force exerted on the beam at the wall (N).

C. Find the vertical component of the force exerted on the beam at the wall (N).
