The cable segment attached to the spring is at an angle of ϕ=20.0° from the ground. The spring has a spring constant of k=16.5 kN/m. The pulley is attached to the ceiling by rod BD that forms an angle θ=55.0° with the ceiling. The hanging mass causes a tension of 3325 N in rod BD.
What is the displacement of the spring?
