Draw the Free Body Diagram for the structure below. 3'-0" A7 Pin support 800 lb 5' 0" 60⁰ 500 lb 3'-0" B 3 Roller

A. A truss member is made with a pair of 4"x 3" x 3/8" angles with the long legs back to back. The angles are 36 ksi steel and are attached at the connection by a 3/8 in. plate running between the angles. The unbraced length is 12 feet and consider both ends fixed. What is the allowable axial load in compression? In tension? How does the compression capacity change if I connect them with a %" plate in between? Does it change tension capacity? (a) 12 C. A 28 foot column is braced top and bottom about the X-X axis and has K bracing as shown on the Y-Y axis only. It is built of A36 steel and is a W12 x 30 section. Can it support an axial load of 165 kips? State its actual capacity.
