The ZFM Analysis Tool is a web-based program designed to assist students in learning how to identify zero-force members in stable statically determinate truss structures. The tool employs a specific set of rules to facilitate the process of identifying and annotating zero-force members in the truss. These rules and their underlying principles are described in Section 7 of this guide.
