Problem 5.7-2 A tall signboard is supported by two vertical
beams consisting of thin-walled, tapered circular tubes (see
figure). For purposes of this analysis, each beam may be
represented as a cantilever AB of length L 8.0 m subjected
to a lateral load P 2.4 kN at the free end. The tubes h

Problem 7.3-9 A shear wall in a reinforced concrete building is
subjected to a vertical uniform load of intensity q and a horizontal force
H, as shown in the first part of the figure. (The force H represents the
effects of wind and earthquake loads.) As a consequence of these loads,
the stresses
