Question

A uniform thin rod of mass m = 3.2 kg and length L = 1.7 m can rotate about an axle through its center. Four forces are acting on it as shown in the figure. Their magnitudes are F1 = 3.5 N, F2 = 4.5 N, F3 = 15 N and F4 = 17 N. F2 acts a distance d = 0.21 m from the center of mass.

Calculate the magnitude τ1 of the torque due to force F1, in newton meters. 
τ1 = 2.975

Calculate the magnitude τ2 of the torque due to force F2 in newton meters. 
τ2 =0.6682
 Calculate the magnitude τ3 of the torque due to force F3 in newton meters. 
τ3 =0

 Calculate the magnitude τ4 of the torque due to force F4 in newton meters. 
τ4 =0

Calculate the angular acceleration α of the thin rod about its center of mass in radians per square second. Let the counter-clockwise direction be positive.
