This file is a technical diagram document illustrating the anatomical components and specifications of a gear, specifically designed for mechanical engineering reference purposes.

The diagram displays a detailed three-dimensional representation of a gear with labeled components including the addendum, dedendum, face width, addendum circle, top land, pitch surface element, face, working depth, flank, pitch circle, tooth thickness, tooth space, circular pitch, total depth, clearance, clearance circle, root or dedendum circle, and the circular pitch measurement. The diagram provides both a technical illustration with dimensional callouts and a photographic image of actual gear components placed alongside a ruler for scale reference. The photograph shows five different gear assemblies in various sizes and configurations, positioned horizontally and measured against a standard ruler marked in inches, demonstrating practical examples of the gear types and specifications outlined in the technical drawing above.
