f₁ F₁₂ f4 f₁ f4 1 USING THIS TABLE, f3 fs 5,000 N fs Figure 1: Distribution of the forces in a bridge. F₂ Joint Horizontal £₁ = $/²2/2 √2 f1 + fu fy = $5 लान =0 2. (a) Write the linear system of equations from problem 1 in the form AF = b, where f = [ƒ1 ƒ2 ƒ3 f4 f5 F1 F₂]™ =0 Neretical £₂ √2 + √2 £₂ = + F₁₂ √3 f3 2 = 50000 1/2/3 6₂ = F₂ (b) What are the orders of A, f and b? Check your answer using the size function in Matlab. Is the system overdetermined or underdetermined or neither? (c) Is it possible to calculate the determinant of A? If so, find it. If not, explain why not. =D
