Springs & Bolted Joints: Spring Rate, Spring Index and Stress, Bolt Preload, Joint Stiffness & Separation Load
This lesson is part of the course
In this lesson
You calculate the rate, index and corrected shear stress of three fictional helical springs, turn a tightening torque into bolt preload and find the external load at which the bolted joint would separate.
