Question

The horizontal beam ABC shown in the
figure is supported by columns BD and CE. The
beam is prevented from moving horizontally by
the pin support at end A. Each column is pinned at
its upper end to the beam, but at the lower ends, support
D is a sliding support and support E is pinned.
Both columns are solid steel bars (E = 30 x 10⁶ psi)
of square cross section with width equal to 0.625 in.
A load Q acts at distance a from column BD.
(a) If the distance a = 12 in., what is the critical
value Q_cr of the load?
(b) If the distance a can be varied between 0 and
40 in., what is the maximum possible value of
Q_cr? What is the corresponding value of the
distance a?
