A traffic light signal pole is subjected to the weight of each traffic signal 45 lbs and the weight of the road lamp 55 lbs . The weight of lateral arms is included in the signal and lamp weights. The people is fixed and the base and is made of round structural steel section HSS 14.000 x 0.25. The details of the pole section may be obtained form the Manual of American society of steel Construction (AISC Steel Manual).
Analyze the principle normal stresses and the maximum shear stresses on elements A and B located at the base in the pole as shown in the sketch below.
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?

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.
