$10^($th $)$ ed$.$ prob. $13-49$ P that can be applied at A without causing it to

buckle or yield. Use a factor of safety of $3$ with respect to buckling and yielding.

E$\_($Al$)=70$GPa and $\backslash$sigma $\_($y$)=95$MPa.

Answer: WRT yielding: P$\_($allow $)=15\mathrm{.}2$kN; WRT buckling: P$\_($allow $)=7\mathrm{.}89$kN $($buckling controls$)$
