I think this question should be pretty simple.
I have a rectangular 2D cantilever beam with an external point load in the downward direction at the free (right-hand) top corner of the beam (the beam is horizontal). The beam cannot delfec in the x- direction because it is constrained with rollers against a vertical wall.
This beam is broken into 2 triangular elements (split by a diagonal line which joins the bottom left corner to the top right. There is a node at each of the four corners of the beam, and the beam is fixed to the wall at its left-hand end.
Im just setting the equations up to anallyse the beam, and i am wondering if the vertiacl forces acting on the two left-hand nodes should both be equal to the applied force in the opposite direction, or both equal to half the applied force?
also would I be right in thinking that a horizontal force would need to act at the bottom left node to balance moments? - this would mean the bottom right element is not in horizontal equilibrium.
Thanks for any help,
