Doug:
Those changes made a
big difference.
Here’s the .jpg of the
Von Mises Stresses. Notice the maximum stress is still in the fillets and
it’s 122,800. psi.
The force is still in
the same flat spot and I increased it to 8500 lb.
That gives you a Safety
Factor of 2.2 over the expected load of 3850 lb.
Ifn you need any more,
let me know.

Jon,
Thanks for all of your
help with the lifting hook. I made some mods and beefed some things
up. If you have a few minutes, please let me know what you
think.
Thanks,
Doug
