QUESTION 3 Rod ABCD is connected to Rod DEFG at D and is also connected by rod BF by pins. A pulley is connected to end G with radius of 0.1m. The rope is hanging around the pulley to hold a mass M1 of 100 kg. The other end of the rope is connected to point C at rod ABCD. Another rod EH is also connected to point E by pin to hold the structure. Point A and point H are also by pin connections to the wall. Points A, B, C, D, H are vertically in-line. Find reactions at pins H and A. (AB = 0.2m, BC = 0.2m, CD = 0.1m, DE = 0.3m, EF = 0.15m, FG = 0.15m, EH = 0.5m, the mass of the rods are neglected). 0.2m B 0.2m Radius Pulley G- 0.Im 0.

Problem. Consider the following problem. Find the displacement of node 4. Assume F2=200 N, F3=300 N, F4=400 N and Kı= 100, K2= 200, and K3= 300 N/mm. F. 3 2 3 4 Note: The stiffness matrix of individual springs should be first written, then the equilibrium equations at each node should be written, expanded in terms of nodal displacement, and used to perform the assembly of the global stiffness matrix of the problem. Then, the appropriate boundary conditions should be applied and the nodal displacement vector should be found. Every step should be shown; missing any step would result in point deduction even if the final answer is correct.
