The figure below shows multiple forces acting at different locations and angles on a wheel. We have magnitudes of F 1 , F 2 F 1 ,F 2 and F 3 F 3 be 20 N, 30N and 20 N respectively. and the wheel has radius r = 1 . 5 r=1.5 m. Image size: SMLMax Part a (1 points) Find the net torque on the wheel about the axis through the center and perpendicular to the plane. (Determine the sign and by treating the positive direction as out of the page) F1 angle is 30 degrees
