I am trying to learn a little bit of this, so if you see any thing wrong please let me know.

While searching through google, I found the equation for shear strength:

tensile strength pounds/in2 x cross sectional area.

In the case of a -10 an bolt with a tensile strength of 160,000 psi and a cross-sectional area of 0.306640625 in2 at the full diameter

160000 pounds/in2 x 0.306640625 in2 = 49062.5 pounds

If 49062.5 pounds is single shear, you double it to get 98125 double shear, right? That should be the amount of force to shear the bolt?


Thanks,
Jon

Your math looks correct! The weak link usually is the rod end not the bolt.
