I've taken the Young's modulus
of structural steel to be 250 MPa or 36.259 ksi. Feel free to
comment if doubtful anywhere before rating..

A design calls for a centrally loaded column consisting of a 12 ft section of square structural tubing. The outside dimension of the tubing is 4 in. and has a 3/8 in. wall thickness. If the design calls for a load of 30 kips, is the column in danger of buckling. What happens if the column is solid and not tubing?

b. A wooden beam made of Western Cedar (Select Structural, use properties for beams) is loaded as shown. It is supported at its ends and via a % in diameter AISI 1020 cold- rolled steel rod at the center. 16 ft - 6 ft- 400 lb/ft TTTTTTTTTTTTTTTI B 12 ft- Find the maximum stress in the rod and in the beam. (Note that the maximum stress in the beam will be due to bending.)

A2 m long column made of structural steel with elastic modulus of 200 GPa is loaded in axial compression. If the cross section of the column is a 20 mm by 50 mm rectangle, and one end is fixed and the other end is pinned, the maximum axial load that the column can bear before buckling, in kN, is (round to the nearest whole number)

A structural tee is used to connect the beam to the column as
shown in the figure. Eight 3/4" - diameter, A325N, fully tightened
bearing-type bolts are used to attach the flange of the tee to the
column flange. Check whether the connection (tee-to-column
connection) is adequate when a dead load of D = 20 kips and live
load of L = 40 kips are applied with an eccentricity of 2.75
inches. All structural steel is A992. Use both Case...

Il): A 25 inches long hot rolled AISI 1025 steel rod is to be subjected to an alternating bending load that will vary from a -5000 lb to +7200 lb as shown in Fig. 1. The properties of this material are given as: the ultimate tensile stress σ,-75,000 psi, the yield stress σ,-48,000 psi. Assume a theoretical stress concentration factor of K-1.65 and the notch sensitivity for this material is q-0.88. The safety factor...
