Question

(PLEASE COMPLETE ALL PARTS OF THE QUESTION)

A uniform thin rod of mass m = 2.9 kg and length L = 1.9 m can rotate about an axle through its center. Four forces are acting on it as shown in the figure. Their magnitudes are F₁ = 5.5 N, F₂ = 2.5 N, F₃ = 11 N and F₄ = 19.5 N. F₂ acts a distance d = 0.23 m from the center of mass.

A) Calculate the magnitude τ1 of the torque due to force F1, in newton meters.

B) Calculate the magnitude τ2 of the torque due to force F2 in newton meters.

C) Calculate the magnitude τ3 of the torque due to force F3 in newton meters.

D) Calculate the magnitude τ4 of the torque due to force F4 in newton meters.

E) 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.
