b) calculate the magnitude T2 of the torque due to force f2 in Newton meters. c) calculate the magnitude t3 of the torque due to force f3 in Newton meters. d) calculate the magnitude t4 of the torque due to force F4 in Newton meters e) calculate the angular acceleration a of the thin rod about its center mass in radians per square second. let the counterclockwise direction be positive.

(8%) Problem 8: A uniform thin rod of mass m - 1.1 kg and length L - 1.3 m can rotate about an axle through its center. Four forces are acting on it as shown in the figure. Their magnitudes are F, in 5.5 N, F, = 1.5 N, F3 = 11 N and FA = 19.5 N. F, acts a distance d = 0.26 m from the center of mass. 60
