Question:

The floor beams AB and BC are stiffened using the two tie rods CD and AD. Determine the force along each rod when the floor beams are subjected to a uniform load w. Assume the three contacting members at B are smooth and the joints at A, C, and D are pins.

Units Used: kip = 103 lb

Given:

w = 80lb/ft

b = 5 ft

a = 12 ft
