QUESTION 1 (5 marks) A 3 m long steel struts connected by simply supported at the ends and is made of a steel tube 80 mm in diameter with a 40 mm bore. The strut is loaded in compression by a force of 35 kN, which is applied parallel to the longitudinal axis. There is an initial curvature to be observed for this strut (E = 210 GN/m², Yield stress = 300 MN/m²). Determine the: a) Moment of inertia, 1. (1 marks) b) The Euler critical buckling load (1 marks) c) The Euler critical buckling load when the strut has lengths of lm, 1.5m, 2m, 4m and 5m. (3 marks)
