attached to the table, the bar can rotate about an axle through point A, B or C. Use F = 20 N, F2 = 30 N, F3 = 25 N, L1 = 1 m, L2 = 0.25 m,L3 == 0.75 m and 0 = 25°. (a) Determine the net torque about axis A. (b) Determine the net torque about axis B. (c) Determine the net torque about axis C. Your answers to all three parts should be expressed in an xyz coordinate system.
