Answer 1

- Sot Given Length of the member l = 10,000mm = com Youngs Modules E= 200000 MPa = 2x 10" N/m2 cross sectional Area A = 4430 mme R Radius r - 132mm (a, Member is pinned - pinned effective length is deal. = criticül buckling Load, Cor = TOET T?x ax 10" x I 11012 I= 4TR4 = 4 * (132)" x(10-34 my - 2.3844*10-4 m+ Acer = 1?x 12x10'') x (2-3844X164) (107² = 4706.6873 KN Car = 4.7066 MN

b, If ends ware Fixed- Fixed effective Length le = f Critical Buchling hood Car = 47°EI da » Love 4x Tr? x 2x10" X 2.3844810-4 102 = 188266 749 kn Cer = 18.826 MN
