Determine the magnitude of the force in the cord AD? Determine the magnitude of the force in the cord AB? Determine the stretch of the spring AB?

Two box hang from the ends of a string suspended from a frictionless pulley. The mass on the left is chosen to create a tension of 4 N in the string. The box on the right has a weight of 2 N. What will be the acceleration of the box on the right? Assume the acceleration of gravity is 9.8 m/s?. 4 N 2 N

Please give a detailed solution. No gpt please.

Answer for part d hint dot the force vector with unit vector along AC

A oil rig tower is held in equilibrium by three ropes. The tension in cable AD is tightened until it reaches 4700 N. Values for the figure are given in the following table. Note the figure may not be to scale. Variable Value d₁ 5 m d₂ 11 m 13.5 m 27.5 m 5m 65 m D d3 d4 d5 de a. Determine the magnitude of the force/tension in cord AB, TAB. b. Determine the magnitude of the force/tension in cord AC, TAC. c. Determine the magnitude of the force developed along the tower, FAE. → i. Hint: FAE = (0 +03+ FAEK) N. Round your final answers to 3 significant digits/figures. The magnitude of the force/tension in cord TAB is N The magnitude of the force/tension in cord TAC is N The magnitude of the force developed along the tower FAE is N
