The cable segment attached to the spring is at an angle of (15 = 50.00 from the ground. The spring has a spring constant of k = 16.5 kN/m . The pulley is attached to the ceiling by rod 80 that forms an angle 0 = 70.00 with the ceiling. The hanging mass causes a tension of 3938 N in rod 80. What is the displacement of the spring? Express your answer to three significant figures and include the appropriate units. b View Available Hint(s) 8 = 0.127 In Previous Answers v Correct Part B, it was shown that the tension in a cable is constant around a frictionless pulley. The reason why the equations equilibrium could be used here is because the values of 0 and 42 are not arbitrary. In fact, the geometry of the system based on the equations of equilibrium and a relationship between 9 and (:5 can be determined using them. Part D - Finding the relationship between \\theta and \\phi Find the relationship between angles 9 and (:5 using the equations of equilibrium and solve for 6. Suppose that the angles are expressed in radians. Express your equation for 9 in terms of 45. Express your answer in radians
