Problem 1: Using the parallelogram law, find the tensile force in cable AC, TAC and the angle a 20° E 0 = 50° W = 1,000 N TAB=600 N Figure Problems 1 & 2 W Problem 2: In Problem 1 what should TAC, TAB and angle a be to minimize the tension TAC? Assume the angle between TAB and the vertical is equal to 60°.Take W = 1,000 N. Hint: Consider various possible force triangles and decide on inspection how to minimize TAC
