The beam is braced at A, B, and C. Determine the lateral-torsional-buckling modification factor, Cb, for the unbraced length AB. Let P = 120 kip, L1 = 14 ft, and L2 = 8 ft.

Use the Steel Construction Manual to determine the plastic moment capacity, Mp, of a W16x57 beam made of A913 Grade 60 steel.

An unsymmetrical flexural member consists of a 3” × 18” top flange, a 3” × 13” bottom flange, and a 1” × 55” web. Determine the distance from the top of the shape to the horizontal plastic neutral axis.

Using the scorecard, rank the two systems in terms of their efficiency in utilizing inputs for fertilization, explain the reasons of your ranking, and state which system of the two is most efficient (max. 200 words). Make sure to include all sources of nutrients (i.e., fertilizers, amendments, N-fixation), the methods used to add nutrients, the approach used to determine if inputs are required or not, and other aspects that can affect nutrient availability and retention.

Determine the maximum deflection for a W14x48 beam made of A913 Grade 65 steel. Let w = 540 lb/ft and L = 27 ft. Ignore the weight of the beam.

What was the Ghost Dance movement? 

Which of the following was Ida B. Wells’s purpose as a journalist and lecturer?

Determine the nominal shear strength of a W14x90 of A913 Grade 65 steel.

Determine the magnitude of the largest shear force (consider both positive and negative peaks). Use a = 22 ft, b = 8 ft, and w = 6 kips/ft. The reaction forces for this beam are Ay = 57.25 kips and By = 122.75 kips.

Determine the nominal shear strength of a W16x36 of A572 Grade 60 steel.
