The body in the figure below is pivoted at o, and two forces act on it as shown.
a) Find an expression for the net torque on the body about the pivot.
I) r2F2 cos θ2 - r1F1 cos θ1
II) r1F2 cos θ1 - r2F1 cos θ2
III) r1F1 sin θ1 - r2F2 sin θ2
IV) r2F1 sin θ2 - r1F2 sin θ1
(b) If r1 = 1.51 m, r2 = 2.03 m, F1 = 3.78 N, F2 = 4.88 N, θ1 = 75.0°, and θ2 = 60.0°, what is the net torque about the pivot?
