Bolted Joint Design: The Difference Between Tension, Shear …
Tensile forces work to stretch/separate the joint, with the tension load adding stress to the bolt. Think of a bolt experiencing tension like a spring. Pull a spring by its end and you'll see it stretch but revert to its original shape when released. But if a spring stretches too far, it remains stretched. In a tension joint, the bolts need ...
