Answer: First of all, I am unable to understand the question. Forward swept wings have a divergence speed which is less than the sweptback wing. Where did you get this Mach number 36?

Answer: Please note that we have applied force at i and moment at j. We are evaluating the total deflection (linear) at 'i' and total angular motion at 'j'. These expressions will be used in the expression for total work done by these two loads. The rotation at 'i' and displacement at 'j' are not required in this case, since there is no associated load (i.e., moment at i and force at j) to provide any work.

Answer: For divergence analysis of swept wing, I normally give an assignment. The solution technique is based on Galerkin method of error minimisation, using the coupled bending and torsion deformation equations. When a request comes from NPTEL, I may have to provide the assignment problems for the entire course.
