13-41. The ideal column has a weight w (force>length) and rests in the horizontal position when it is subjected to the axial load P . Determine the maximum moment in the column at midspan. EI is constant. Hint: Establish the differential equation for deflection, Eq. 13-1 , with the origin at the mid span. The general solution is v = C1 sin kx + C2 cos kx + (w/(2P))x2 - (wL/(2P))x - (wEI/P 2) where k2 = P/EI. | |
