Figure shows the lines of action and the points of application of two forces about the origin 0, all vectors being in the plane of the figure. Imagine these forces to be acting on a rigid body pivoted about an axis through 0 and perpendicular to the plane of the figure. (a) Find an expression for the magnitude of the resultant torque on the body. (b) If r 1 = 1.30 m, r 2 = 2.15 m, F 1 = 4.20 N, F 2 = 4.90 N, θ 1 = 75.0°, and θ 2 = 58.0°, what are the magnitude and direction of the resultant torque?
