Determine the limiting laterally unbraced length for the limit state of inelastic lateral-torsional buckling, Lr, for a W16x36 with a simple span of 22 ft if lateral bracing for the compression flanges is provided at the ends only. Use Fy = 45 ksi.

Which of the following is true about the Red Scare of 1919–1920? 

Determine the maximum deflection for a W14x61 beam made of A572 Grade 42 steel. Let P = 5,700 lb and L = 20 ft. Ignore the weight of the beam.

Using ASD, determine the allowable shear strength of a W12x120 made from A992 steel.

To combat communism, one of John Kennedy’s first acts was to

What was the goal of the policy of appeasement? 

Determine the limiting laterally unbraced length for the limit state of yielding, Lp, for a W16x36 with a simple span of 14 ft if lateral bracing for the compression flanges is provided at the ends only. Use Fy = 75 ksi.

Shear is usually a problem in rolled steel beams; the usual practice is to design a beam for shear and then to check flexure.

Using ASD, determine the nominal flexural strength of a W16x45 beam made from A992 steel that has lateral support at 3-ft intervals. Assume Cb = 1.0.

The word “Progressivism” came into common use around 1910
