study steering bicycle

[M_free]

good morning to all, I am studying the forces acting on the steering rod of a very particular bicycle. In fact, there are two flanges where the tubes of the bike are uncertain (the horizontal one and the one below). I have reported all the forces coming from the handlebar and the fork on the axis of the canton, which therefore is loaded above and below. The problem is to bring back the configuration of loads and constraints from a 3d system (in figure) to study 2d to solve the iso/hyperstatics.thanks to everyone!

I understand that time is by sea, but... "cannotto", not "canot", although it is a rather common mistake.

all 3d loads will go on body 3d. If you think it can be assimilate to a 2d structure you do nothing but impose dimensions equal to zero (like your vertical tube diameter) and then as you schematized in 2d you have the beam. where the forces were applied must be reported in box 2d. I don't think it's so hard
