Select the lightest W section to carry an axial compression of 90 kips dead load and 320 kips live load. The member is part of a braced frame. The idealized support condi- tions are that the member is hinged in both principal directions at the top of a 30 f height; supported in the weak direction at 1- and 22 ft from the bottom; and fixed in bot directions at the bottom. Use (a) A992 steel
