Question:

Three hikers are shown crossing a footbridge. Knowing that the weights of the hikers at points C, D, and E are 200 lb, 175 lb, and 135 lb, respectively, determine

(a) The horizontal distance from A to the line of action of the resultant of the three weights when 3.3 Î± = ft,

(b) The value of a so that the loads on the bridge supports at A and B are equal.

- 18 ft- -45 n-a---150–-| -15e- 4.5ft C. в
