P.14.16
A column has the cross section shown in Fig. P.14.16 and carries a compressive
load
P
parallel to its longitudinal axis. If the failure stresses of the material of the col-
umn are 4 and 22 N
/
mm
2
in simple tension and compression, respectively, determine
the maximum allowable value of
P
using the maximum normal stress theory.
