Case Study 1: Outdoor Support Column (note: this question is worth 2 marks) 2r H A column of specified height, H, is fully fixed at its base and must support a compressive load, F, at its other end without buckling. The cross-sectional area is unconstrained. It must be at least acceptably durable to fresh and salt water, as well as exposure to acid rain (10% sulphuric acid). Its cost (£) is to be minimised.
