The Basic Finite Element Equation

by Peter Kwok, '96 and Prof. Joseph J. Rencis, Advisor

A single degree of freedom translational spring will be used to introduce the force-displacement equation that is continuously encountered in the finite element method. In addition, the spring will also be used to introduce the concept of stiffness and degrees of freedom.
