The side plating of an aluminium alloy deckhouse 2.28 m high is subjected to an average longitudinal compressive stress of 30.9 MN/m². The aluminium alloy has E = 69500 MN/m². Find the required thickness to give a factor of safety of 1.5 against initial buckling if (a) The deckhouse side is stiffened only be vertical frames 760 mm apart. (b) In addition to (a), horizontal stiffeners, spaced 870 mm apart, are fitted.
