Extracted text: A W14 x 38 column of A992 steel is fixed at its base and pinned at its top. (a) If L = 22 ft, determine the largest axial force P that can be applied without causing buckling or yielding. (b) Repeat part (a) if L = 8 ft. (c) Determine the length L such that Euler's critical load for buck- ling equals the load that causes yielding; i.e., Per = Py.
