Most engineers who deal with bolted joints are familiar with torque tables for SAE-grade bolts, but these are all too often used without regard for the yield strength of internal threads or the bolt’s ...

One of the most critical factors in determining the reliability of a threaded-fastener joint is the force the tightened fastener exerts on an assembly, which is known as preload. And preload depends ...

Stress is defined as the force per unit area. Thus, the formula for calculating stress is: Where σ denotes stress, F is load and A is the cross sectional area. The most commonly used units for stress ...
