2. For the shown structure, use the stochastic optimisation method of SPSA to find the lengths of members 2 and 3 which minimise the forces in links 4 and 5. Note the following constraints, 2.4m ≤ AB ≤ 3.5m and 2.8m ≤ AD ≤ 4.5m Solve the problem for the force angle taken as 90 deg, 120 deg and 180 deg. Note the angle made by link 2 with horizontal for every case and comment on the outcomes of the three runs. B E 2 3 KN 0₂ EB = 0.3 m BC = 2.44 m CD = 2.5 m (3 106 2.
