(8%) Problem 7: A uniform thin rod of mass m = 2.4 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 F = 3.5 N, F2 = 1.5 N, F3 = 14.5 N and F4 = 18 N. F₂ acts a distance d = 0.18 m from the center of mass. 20% Part (a) Calculate the magnitude Ty of the torque due to force F₁, in newton meters. Tj = 3 ✓ Correct! 20% Part (b) Calculate the magnitude 72 of the torque due to force F₂ in newton meters. T₂ = 0.19 ✓ Correct! 20% Part (c) Calculate the magnitude 73 of the torque due to force F3 in newton meters. T3=0✔ Correct! 20% Part (d) Calculate the magnitude 74 of the torque due to force F4 in newton meters. T4=0 ✓ Correct! F₂ α = F3 45° 60° 4 F₁ Otheexpertta. ► 20% Part (e) Calculate the angular acceleration a of the thin rod about its center of mass in radians per square second. Let the counter-clockwise direction be positive. Grade Summary Deductions Potential
