Question

2. Buckling. (10pts) The A-36-steel W12 x 50 column is fixed at its base. Its top is constrained so that it cannot move along the x-x axis but is free to move along the y-y axis. Determine the allowable centric load the column can support if the safety factor is 2. Data: A= 1 Sin, 1, = 56in, 1.-394 in*, E-29x10,ksi.
