For the minimum-mass tubular column design problem formulated in Section 2.7, consider the following data: P = 50 kN; I= 5.0 m; modulus of elasticity, E =210 Gpa; allowable stress, oq = 250 MPa; mass density p= 7850 kg/m?. Treating mean radius R and wall thickness t as design variables, solve the design problem graphically, imposing an additional constraint R/t s 50. This constraint is needed to avoid local crippling of the column. Also impose the member size constraints as 0.01
