Problem 3 - The system of forces shown is at equilibrium. a) Draw FBDs at points \( \mathrm{C} \) and D. b) Find the tension in cables \( \mathrm{AC} \), \( B C \), and \( C D \) using i) Force triangle and ii) equilibrium equations. \( \left(\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^{2}\right) \). (25 pt.) Problem \( 4-\mathrm{A} 200 \mathrm{~N} \) weight is suspended as shown. a) Draw the Free Body Diagram of Point \( \mathrm{C} \). b) Find the tensions in cables \( \mathrm{AC} \) and \( \mathrm{BC} \). c) To minimize the tension in cable \( \mathrm{AC} \), would you move point A up or down or keep it the same? Why? (20 pt.)
