A W14x61 made with A992 steel is pinned at both ends and braced in the weak direction as shown. Can it support a dead load of 120 kips and a live load of 120 kips? Use LRFD. Let L1 = 24.4 ft, L2 = 8.4 ft, and L3 = 16.0 ft.

A column is fabricated by bolting a 3/4 x 6 plate to the top and bottom of a W14x82. Determine the moment of inertia about the y axis.

A column is fabricated by bolting a 1 x 6 plate to the bottom of a W14x370. Determine the distance from the bottom of the plate to the centroid of the composite cross section.

In the first Abilene Paradox video (animated), how was the drive to Abilene described?  

The designer should provide extra support for the weak direction of a column. Otherwise the member will be inefficient.

A W14x74 made with A992 steel is pinned at both ends and braced in the weak direction as shown. Can it support a dead load of 240 kips and a live load of 240 kips? Use LRFD. Let L1 = 24.4 ft, L2 = 8.4 ft, and L3 = 16.0 ft.

The hormone that is most associated with a fall in blood glucose when it is released into the bloodstream is:

If a compression member is supported differently with respect to each of its principal axes, the effective length will be the same for both directions.

Determine the effective length factor, Kx, for column FG of the frame, assuming that the frame is sidesway inhibited and that all of the assumptions on which the alignment charts were developed are met.Girders BF, CG and DH are W18 x 46 and have a length of L1 = 20 ft.Girders FJ, GK and HL are W21 x 50 and have a length of L2 = 28 ft.Columns AB, EF and IJ are W10 x 54 and have a length of L3 = 16 ft.Columns BC, FG and JK are W10 x 45 and have a length of L4 = 12 ft.Columns CD, GH and KL are W10 x 33 and have a length of L4 = 12 ft.
