Please do for me question 2.3 up to 2.7

Question 2 The box with weight W is supported by the cable system consisting of cables AB, D 3 AC and AD. Determine the maximum 45° weight that the box can take so that none of the cable tensions exceed 200 N. 60° 120° In this problem, no restriction is given on the vertical cable that carries the weight W and we assume that the tension in the vertical cable may exceed 200 N. 30° B W The general procedure to answer the question will be to solve an equilibrium problem (Questions 2.1, 2.4 and 2.5) and make the relevant conclusions from the solution (Question 2.6). Question 2.7 illustrates that the remaining cable forces do not exceed 200 N. 2.1 Draw the FBD for the connecting ring A and let TB, Tc and Tp denote the forces that cables AB, AC and AD exert on A respectively. 2.2 Check that the direction angles for Tp form a valid set of values. 2.3 Express TB, Tc and Tp in cartesian vector form. 2.4 Write down a system of equilibrium equations in scalar format that ensures equilibrium of A. 2.5 Solve the system in Question 1.4. Express your answer in terms of W. 2.6 If the maximum tension that each of the cables can resist, is 200 N, determine the maximum W for equilibrium. 2.7 Calculate the tensions in cables AB, AC and AD to convince yourself that none of the forces exceed 200 N.
