Please help. Provide Free Body Diagram, labeled with appropriate quantities to better understand. Also solve. Thank you.

The truss is supported by a pin at A and a roller at B and loaded with three equal loads ,F1​=F2​=F3​=11kN. Calculate the support reactions FA​ and FB  Find the forces in the members S2​, S​, and S11​ using the method of sections.

25 KN Using the method that has been covered, find the displacement of the node 2 if E1 = 100 GPa and A1=10-6 m² and E2= 200 GPa and A2=2x10 6 m². N2 5 cm 2 30° N3 N1, Note: The stiffness matrix of individual elements 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
