A horizontal beam AB is supported at end A and carries a load Q at joint B, as shown in the figure part (a). The beam is also supported at C by a pinned-end column of length L. The column has flexural rigidity EI.
(a) For the case of a guided support at A (figure part (a)), what is the critical load Qcr (In other words, at what ? load Qcr does the system collapse because of Euler buckling of the column DC?
(b) Repeat (a) if the guided support at A is replaced by column AF with length 3L/2 and flexural rigidity EI (see figure part (b)).
