Question: Calculate the critical load Pcr for a W 8 ( 35 steel column (see figure) having length L = 24 ft and E = 30

Calculate the critical load Pcr for a W 8 ( 35 steel column (see figure) having length L = 24 ft and E = 30 ( 106 psi under the following conditions:
(a) The column buckles by bending about it's strong axis (axis 1-1), and (b) the column buckles by bending about its weak axis (axis 2-2). In both cases, assume that the column has pinned ends.
