calculation forces of a trailer

[Ciccio1907]

Good morning I wanted to ask for an opinion to determine the forces discharged from the trailer on a drive (tractor). I would like to determine precisely the axial force and the cutting force that acts on the drive hook, I thought to consider for both cases the weight of the entire trailer, but I do not think it is right. Does anyone know how to do that? the problem arises from the fact of verifying screws as in the photo (in attachment an image found on the web, but my problem is equal).
thanks to all those who will help me

the weight of the trailer will be discharged on the wheels and on the hook.
it is necessary to keep in mind holes, shocks etc.
for traction consider weight, slope, acceleration etc.
However, it is necessary to refer to the specific regulations for the towing hooks.

Can you tell me the rules you refer to? Where can I find them?

look for the discussions we have already made on the forum about the towing hook.
