Mr Gadwantikar, your explanations have really helped me a lot. In fact, a mountainous amount of guidance I would say. You have explained way more clearer than my lecturers and finding a channel that would have all the videos of finite element method readily is a big rarity. Keep going ahead with more good stuff. Thank you very much.

Dir sir. The form of stiffness matrix already deals with global coordinates x @ y . So u3 and v3 must be considered in x and y and not as indicate by the mister . Therefore u3 and v3 have a displacements tword x and y . I.e, v3 not zero. Thanks

How come does V3 equal to 0 at 22:52 ? That roller at node3 makes an angle of 45 degree with global coordinate system. You just edit global K matrix with respect to local coordinate system at node 3. I believe this is a mistake, if not please explain this.

Before any boundary condition implementation, transformation should be made at the roller support with an angle. By doing this, corresponding component of the K matrix are transformed to local coordinate system with respect to corresponding element. After that boundary conditions will implemented. Solving the system will result transformed results for that node. Retransformation should be done to obtain results in global coordinate system. Tomorrow I will share a book which describes this procedure.
