## Description

**Theory of Machines** is an offline educational app for mechanical engineering students, diploma and polytechnic learners, beginners, and users preparing for exams, vivas, interviews, workshops, or technical revision. It covers 15 subjects, including kinematic pairs, chains, degrees of freedom, velocity and acceleration, inversions, belts, chain drives, cams, gears, gear trains, governors, flywheels, friction, clutches, brakes, vibrations, and applied mechanisms.

The app also includes 21 free machine tools for calculating mechanisms, piston motion, velocity, acceleration, gear ratios, gear trains, torque, mobility, Grashof mechanisms, gear dimensions, and more. With 60 practical How-To lessons, searchable content, bookmarks, and offline access, it provides a convenient reference for understanding machine motion, power transmission, and mechanical systems. It is intended for educational support, with results best verified against textbooks, lab manuals, and engineering standards.
