Problem 3-28

The street-lights at A and B are suspended from the two poles as shown. If each light has a weight of 50 lb, determine the tension in each of the three supporting cables and the required height h of the pole DE so that cable AB is horizontal. Step-by-Step Solution

Step 1 of 2

Use the sum of the forces to solve for all forces in terms of the given angles, then solve for the unknown angle to solve for the height h.

At point B.     Step 2 of 2
