Cantilever Beam - which model best represents?

Cantilever Beam - which model best represents?

Cantilever Beam - which model best represents?

(OP)
Hi there,

I have a setup as shown in the following schematic: https://files.engineering.com/getfile.aspx?folder=...
The 'cantilever beam' sits laterally onto another 'support beam' with two bolts holding it.
Originally I modelled it simply as the two bolts as pinned supports, but now I think the 'support beam' edge should be a third pinned support??
As this 'support beam' is also supporting downward force?
The model of two bolts is follows: https://files.engineering.com/getfile.aspx?folder=...
The model of two bolts and 'support beam' is as follows: https://files.engineering.com/getfile.aspx?folder=...

Thoughts?

Thanks,

RE: Cantilever Beam - which model best represents?

hello

The model with two reactions at each bolt is most accurate. Except the bolt further from the pivot will take the most load. In proportion to its distance from the pivot. As the stretching and tension in bolt will be more.

This assumes no bending of the beam to the right of the pivot, which is not fully true, but accurate enough.

There will always be a load at a pivot point or line

RE: Cantilever Beam - which model best represents?

Neither model is correct. The edge of the support beam will be an upward reaction, and the bolt furthest from the edge of the support beam will be in tension.
