Hydraulic cylinder question
Hello !
I am working on a project with to antagonistic hydraulic cylinders. They both have two brackets with two screws each, i.e 8 screws in total.

how do I calculate the load(forces) that will affect the screws once the cylinders are moving?
I also added an image to make it easier for you guys to understand.

Are you saying you don't know how to calculate the force generated by a hydraulic cylinder? Or is your question something else?

[COLOR=#333333]Assuming there are four "all-thread" studs located equally-ish spaced the shear force applied to each stud would be (Force applied by cylinder max)/4 in a perfect world.[/COLOR]

For the single and double shear force/stress applied to each stud see:

The "all-thread" studs are not meant for large shear loading, you should consider a bolt or stud where the loading is applied to a bolt grip area.

"all-thread" studs are best used for compression and tension loading
