Find the net torque on the wheel in the figure below about the axle through O perpendicular to the page, taking a = 7.00 cm and b = 23.0 cm. (Indicate the direction with the sign of your answer. Assume that the positive direction is counterclockwise.)
The torque produced by the 10 N force is τ = 10 •0.23 = -2.3 (N•m), The torque produced by the 9 N force is τ = 9 •0.23 = -2.07 (N•m), The torque produced by the 12 N force is τ = 12 •0.07 = 0.84 (N•m) The total torque is τ =-2.3 - 2.07 +0.84 = -3.53 (N•m).
