I can not sem to find an answer to my question in the 26th addition of the machinery handbook.
We have an aluminum nut (threaded onto a steel shaft) that is 16mm with a .1 thread pitch and has 7 threads of engagement. This nut holds it all together . it is a shock absorber of sorts. The spring pulls the shock to full extension and a top out plate that the nut holds on hits the seal head and it is at full travel and the only pressure on the nut -- besides the 25 ft lbs it is torqued to is the stored energy of the spring.
So my question is how much spring force will the aluminum (7075) nut take before the threads shear off ???
Thanks for your help!
