I need quick help

The gure above is the FBD of the horizontal part of a seesaw of negligible mass that is being . pushed (up, down, and sideways) by ve different people, represented: by the five external forces acting on the seesaw (F1 through F5). Except for F1, which acts parallel to the seesaw, and F4, which acts at an angle 6 of 30.0", these external forces are perpendicular to the seesaw. FF is the supporting force exerted by the seesaw's pivot. The seesaw is perfectly balanced as shown. For this problem, rL, rR, and F2 are all known. By following the lettered sections below, you will find Fp. Hint: what pivot point should you use? (A) Redraw and label the FREE BODY DIAGRAM of the horizontal part of the seesaw, showing ail the external forces that are acting on it. Each external force must be represented by an arrow that is properly labeled and includes its angle (if any). Be sure to show explicitly the x and y coordinate system you will use as well as the pivot point around which you will apply the second condition for equilibrium. (B) Referring to your redrawn FREE BODY DIAGRAM of the 'seesaw and to your chosen pivot point, write the second condition for equilibrium for this system, simplify it, and then derive an equation that solves for Fp in terms of the other variables. (C) 'ler = 1.60 m, 17; = 0.950 m, and F2 = 115 N, nd Fp to three signicant gures
