1. An elongated member comprising:
an elongated body having an outer surface defined about a central longitudinal axis, said outer surface defining a first recess section about at least a portion of said body; a first fitting coupled to a first end of the elongated body for applying a compressive load to said elongated body along said central longitudinal axis; and a second fitting coupled to a second end of the elongated body opposite the first end for applying a compressive load to said elongated body along said central longitudinal axis, wherein said elongated bodyLerminπ2Eσy  is greater or equal to 0.5, wherein: L=Length of the elongated body Le=Effective Length of the elongated body Imin=Minimum Second Moment of Inertia of the elongated body A=Cross sectional Area of the elongated body rmin=Minimum Radius of Gyration of the elongatedbody=IminA σy=Yield Stress of the elongated body E=Modulus of Elasticity of the elongated body.
