The angle between the rod and the beam is θ and the distance between points A and B is L.

B) Let the tension in the cable be T = Ti. Enter a vector expression for the torque T1 on the rod about the hinge due to that tension, in terms of T, L, θ, and the unit vectors i, j, k.

C) Given the values T = 399 N, L = 9.1 m, and θ = 21°, calculate the magnitude of the torque T1, in newton meters.

D) A force F = -Fj acts on the rod at point C, whose distance from the hinge is fL, 0<f<1. Refer to the figure. Enter a vector expression for the torque T2 on the rod about the hinge due to the force F, in terms of F, L, f, θ, and the unit vectors i, j, k.

E) For the values L = 9.1 m, θ= 21°, T = 399 N, and f = 0.84, calculate the magnitude F of the force F, in newtons, needed to balance the torque from the tension in the cable.
