A horizontal beam AB is pin-supported at end A and carries a load Q at joind 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 pare (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 3/L2 and flexural rigidity EI (see figure part (b)).
