I get that the tending stress is roughly (Mc/I = 12Mc/bh^3, c=.5, b=.25, h =1, M= 150lbs at 2in = 300in-lbs) = 7200psi add in normal stress of (F/A = F/bh) = 600 psi and you are still under 8,000psi. Well under Aluminum's yield stress.

I don't see buckling being a problem... ...plenty strong for me.
