Question details

PROBLEM 2.47 Knowing that α (b) in rope BC. 200, determine the tension (a) in cable AC, 200 1 SOLUTION Free-Body Diagram Force Triangle zoolb 200lb 1200 lb sin 110 sin 5 in 65 T. Law of sines: 1200 lb sin 65° 1200 lb in 65 sin 110 TAC = 1244 lb sin 5 TBC 15.4 lb

May can you please explain how we got (sine 110) for TAC/Sin110 and how Tbc is (sine 5)?

Can you also explain how to construct the force triangle?

Thank you!
