Question:

Three hikers are shown crossing a footbridge. Knowing that the weights of the hikers at points C, D, and E are 800 N, 700 N, and 540 N, respectively, determine

(a) The horizontal distance from A to the line of action of the resultant of the three weights when a = 1.1 m,

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