Question: A 3 5 ft . column is fixed at the top and fixed at the bottom, and has additiona pinned supports in the weak axis

A 35 ft. column is fixed at the top and fixed at the bottom, and has additiona
pinned supports in the weak axis direction at points 10 ft. and 20 ft. from the bottom. Assume the column is part of a braced frame. Axial gravity loads are PD =190 kips and PL =250 kips. Use
Design tables of the AISC Manual to choose the lightest W10
