SUMMARY
The summation of torques equation for Figure P8.4 is derived by considering the forces acting on the object and their respective distances from point O. The equations established are ΣFx = -Rx + Fx = 0, ΣFy = Fy + Ry - Fg = 0, and the torque equation Στ requires the calculation of perpendicular distances from point O for forces Fg, Fy, and Fx. The distance 'l' is treated as the hypotenuse of a right triangle, which is crucial for determining the torque contributions of each force.
