PRELIM EXAMINATIONS STRUCTURAL THEORY 1

Name: __________________________________________________________ Course/Yr.: _____________

PROBLEMS:

1. A sign is subjected to a wind loading that exerts horizontal forces of 300 lb on joints B and C of one of the side supporting trusses. Determine the force in each member of the truss and state if the members are in tension or compression.

2. The beam will fail when the maximum moment is Mmax = 30 kip-ft or the maximum shear is Vmax = 8 kips. Determine the

largest intensity w of the distributed load the beam will support.

3. Draw the shear and moment diagrams for each member of the frame. Assume the support at A is a pin and D is a roller.
