Question

please solve problem 4.81 with Matlab or Excel by using data from problem 4.80.

please the information is provided below, starting from data:

4.80 A minimum weight tubular column design problem is formulated in Section 2.7 using mean radius R and thickness t as design variables. Solve the KKT conditions for the problem imposing an additional constraint R/t s 50 for this data: P 50 kN,1-5.0 m, E 210 GPa, ơ.-250 MPa and 7850 kg/m3. Interpret the necessary conditions at the solution point graphically. 4.81 A minimum weight tubular column design problem is formulated in Section 2.7 using outer radius Ro and inner radius R, as design variables. Solve the KKT conditions for the problemn imposing an additional constraint 0.5(R, + R)/(R,-R.) 50 Use the same data as in Exercise 4.80. Interpret the necessary conditions at the solution point graphically problem imposing an additional constraint R/t 50 for this data: P = 50 kN, 5.0 m, E> 210 GPa, o,-250 MPa and ρ-7850 kg/m3.
