I am trying to design a breakaway Bolt, is there an equation to calculate how much torque is required to break the head of the bolt. Typically this bolt has two heads, one that breaks off and the permanent one. These are connected with a small neck that breaks at a given torque. That's what I need to calculate, the diameter needed to break at 40 ft-lbs.(adsbygoogle = window.adsbygoogle || []).push({});
