Three forces are applied to a wheel of radius 0.350 m, as shown in the figure (Figure 1). One force is perpendicular to the rim, one is tangent to it, and the other one makes a 40.0∘ angle with the radius. Let F1=12.3N, F2=14.4N, and F3=8.70N. What is the net torque on the wheel due to these three forces for an axis perpendicular to the wheel and passing through its center? Let counterclockwise torques be positive.
