When an interaction formula is greater than one, the _______.

Compute the ASD elastic critical buckling strength, Pe1, for the W14x74 made from ASTM A992 steel with L = 16 ft, P = 200 kip, M = 260 kip-ft, and Kx = Ky = 1.0. Bending is about the x axis. The member is part of a braced frame, and the given service loads are 40% dead load and 60% live load. The frame analysis was performed consistent with the effective length method, so the flexural rigidity was unreduced.

Free radicals are highly reactive molecules and can form adducts with which components of the cell?

Identify the correct stiffness reduction factor for the direct analysis method.

Many isolated one-story columns can be realistically treated as fixed at both ends.

Compute the value of Cm for a beam-column in reverse-curvature bending with a moment of 140 kip-ft on one end and a moment of 590 kip-ft on the other end.

Compute the LRFD moment amplification factor B1 for the W18x65 made from ASTM A992 steel with L = 16 ft, P = 230 kip, M = 220 kip-ft, and Kx = Ky = 1.0. Bending is about the x axis. The member is part of a braced frame, and the given service loads are 30% dead load and 70% live load. The frame analysis was performed consistent with the effective length method, so the flexural rigidity was unreduced.
