Good point Harry, I was thinking that myself after looking at some of these examples in my old text books. I can measure the rod at 0 torque or pre-torque behind the nut and then apply the 20-25 ft-lbs. Then a second measurment which should give me a decent indicator of how much displacment...
Well with a load that high I can see that using a cam lock with an 8" lever on it would be almost impossible to create that force by a normal human.
...hmmm.
Wow, that is much greater than expected. Can you tell me or where can I find the formula's so I can try some different sizes. I thank you very much for this.
I need some help designing an I.D. mandrel clamp for a prototype machine.
In order to clamp our mandrel to an I.D. of a tube 20 ft-lbs of torque is needed (measured from a torque wrench). The lead screw is a 5/16-18 B7 All Thread and the torque wrench was turning a 5/16-18 hex nut at the...
