Assuming a classic supply and demand model for good “X”, an increase in the prices of resources used to produce X will: increase S, increase P, and increase Q. increase D, increase P, and increase Q. decrease S, decrease P, and decrease Q. decrease S, increase P, and decrease Q
Read DetailsCompute the LRFD elastic critical buckling strength, Pe1, for the W14x74 made from ASTM A992 steel with L = 12 ft, P = 480 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 using the requirements for the approximate second-order analysis method meaning that a reduced stiffness was used.
Read DetailsUsing ASD, determine the value of the AISC interaction equation for a W12x106 made from ASTM A992. Let L = 16 ft, Kx = Ky = 1.0, and Cb = 1.0. The factored loads are Pnt = 110 kip, Mnt = 180 kip-ft, The member is part of a braced frame, bending is about the x axis, and the ASD moment amplification factor has been determined to be B1 = 1.031.

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.
