Question

Please HELP!!! Determine the torque produced about the support A of the rigid structure, shown in the figure (Figure 1) (pic of figure in comments), as a function of the leg angle θ if a force F = 500N is applied at the point P perpendicular to the leg end. Graph the values of the torque τ as a function of θ from θ= 0∘ to 90∘ in 10 ∘ increments.
