Helical Compression Spring Calculations

The information presented in this blog post is for educational purposes only. It should not be used for engineering design or relied upon as engineering advice.

The editable EngineeringPaper.xyz sheet below (this sheet may also be opened in a new tab) allows you to calculate the key design parameters for a helical compression spring (stiffness, shut length, and max shear stress).
