a=0.18 m B C A 0.4 m -0.4 m- 0.24 m D PROBLEM 4.19 (Questions 3-4 in the McGraw-Hill Connect Section 4.1 HW assignment.) The bracket BCD is hinged at C and attached to a control cable at B. For the loading shown, determine (a) the tension in the cable, (b) the reaction at C. Strategy: Apply equilibrium to solve for the tension in the cable and the reactions at C. Model: Draw a free-body diagram that could be used to calculate the tension in the cable and the reactions at C. Analysis: Using the free-body diagram in the Model step, generate the equilibrium equations that are needed to solve for the requested unknowns. Count the equations and the unknowns as we do in the example problems. Remember that all variable names must be consistent with the labels used on the free-body diagram, as the free-body diagram is a pictorial representation of your equilibrium equations. (You do not need to solve for the unknowns in this written assignment as you did that in the McGraw-Hill Connect homework assignment.) Reflect and Think: Generate another equilibrium equation to perform a check on the results. What are the limitations of using this method to check your results? How does the methodology of Section 4.2 related to two-force members and three-force members apply to this problem? Could the methodology of section 4.2 be used to check your solution to this problem? Explain. Grading Criteria: The grading rubric is below. Problem 1 Proficient (3) Model Includes accurate and complete model. Emerging (2) Missing a few parts of the model and/or a few parts of the model are inaccurate. Needs Improvement (1) Missing many parts of the model(s) and/or many parts of the model(s) are insecuestr Not Attempted (0) Not attempted.
