Finding the Center of Mass of a Soft Spring
arXiv:1005.3881 · doi:10.4169/college.math.j.42.5.389
Abstract
This article shows how to use calculus to find the center of mass position of a soft cylindrical helical spring that is suspended vertically. The spring is non-uniformly stretched by the action of gravity. A general expression for the vertical position of the center of mass is obtained.
