(10\%) Problem 8: A uniform thin rod of mass m=3.9 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=6.5 N,F2=3.5 N,F3=14 N and F4=17.5 N.F2 acts a distance d=0.25 m from the center of mass: A 20% Part (a) Calculate the magnifude r, of the torque due to force Fj, in newton meters. Hints: 3, deduction per hint. Hints remaining: 2 Feedback: 2 be doduction per feedback. A 20\% Part (b) Calculate the magnitude τ2 of the torque due to force F2 in newton meters. A 20% Part (c) Calculate the magnitude r3 of the torque due to force F3 in newton meters. a 20% Part (d) Calculate the magnitude τ4 of the torque due to force F4 in newton meters. a 20% Part (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.
