A bar of hollow circular cross section has an outer diameter of 50 mm, an inner diameter of 40 mm, and a length of 3 m. The bar is used as a structural member in a pin-jointed framework, and an analysis has shown that it is subjected to a compressive axial force of 500 N. As part of a buckling analysis, assuming the bar is pin-jointed at each end, the effective slenderness ratio is then:
