Offset clamping force
Offset clamping force
(OP)
Evening all,
I've been working on some clamps, and although they have been tried and test (previously, we are reusing) it got me wondering. How would i calculate out an offset clamping force. I've attached an image as an example. So if i applied a tightening force on the nut what would be the applied force on the end of the hook. There is no tightening force, it could be anything for the pupose of this example.
Thanks in advance, i need to keep my brain working otherwise it stops and i can't figure this sort of thing out!!!!!!

I've done work previously on the lever type, where you pivot in the centre and have 1 to 1 clamping force. Then in some instances you can't get the pivot in the centre either the force or the clamp end moves and calculate that out. Think this one is a little different.

Bolt torque vs axial tension.

@kiwiton I have been on that page earlier however this is for calculating straight forces? I've been using that also. I think another way to look at it is like the attached. A rough sketch of my clamp.

The problem with sloppy work is that the supply FAR EXCEEDS the demand
RE: Offset clamping force
I think you should just simplify it and not assume there is an offset between 'clamp point' and 'bolt point'.
I dont have any experience with this type application, so I am a bit like you, but I would suggest the offset is minimal compared to the torque and axial forces.
Basically, the torque applied by the nut will be transmitted through the curved clamp and back into the base material.
