The cable segment attached to the spring is at an angle of ϕ=50.0∘ϕ=50.0∘ from the ground. The spring has a spring constant of k=15.5 kN/mk=15.5 kN/m . The pulley is attached to the ceiling by rod BD that forms an angle θ=70.0∘θ=70.0∘ with the ceiling. The hanging mass causes a tension of 3933 N3933 N in rod BD. What is the displacement of the spring?
