1.5 m 0.5 n 2 m 30 mm 20 mm A 30 mm 1 of 1 Part A Determine the maximum allowable intensity $w$ of the distributed load that can be applied to member $BC$ without causing member $AB$ to buckle. Assume that $AB$ is made of steel and is pinned at its ends for $z$ axis buckling and fixed at its ends for $y$ axis buckling. Use a factor of safety with respect to buckling of 2.20. $E = 200 \text{ GPa}$, $\sigma_Y = 360 \text{ MPa}$.
