I have the scenario where I wish to model the movement of a simply supported beam under a central point load. I've done some stuff in R Studio to come up with deflection plots and that's fine. In reality though, I have a pair of parallel beams (similarly supported and loaded) but when they deflect, I want to investigate the behaviour of some points which are referenced to one of the beams' surface by an angular offset to perpendicular.
Imagine the setup in the diagram. The parallel straight beams have two lines (x, y) which leave the top beam at angles A & B. I am interested in the lengths x and y after the beams have deflected (as I have poorly shown) - x', y' are going to be different to x,y - this I appreciate, but I would like to model it somehow.
I believe that something like Solidworks will do this for me, but it's expensive. I can also start from scratch and do something in python or R, but I was wondering what open source or low cost modelling software might exist which would allow me to do this (in the same way that Solidworks might - but without all the other stuff that Solidworks does!)
