KIGAKU is a visual learning app that teaches how machines work by letting you move them. How do teeth change speed and torque? Why can a pulley or screw turn a small force into a large one? Move a slider and the mechanism responds at once, with its results updating alongside. The formulas in your textbook connect to motion you can see. [Transmit power] - Gears: how tooth counts set speed and torque - Belt drive: pulley diameter and speed ratio - Planetary gear (new): hold a different part for reduction, overdrive, or reverse [Multiply force] - Pulleys: rope count, required force, and pull distance - Lever: fulcrum position and balance of moments - Screw: turning torque into thrust, and efficiency - Hydraulics: Pascal's principle and piston area ratio [Convert motion] - Linkage: four-bar paths and Grashof's condition - Cam: shapes that turn rotation into lift - Crank: converting rotation and reciprocation - Geneva drive (new): turning steady spin into stop-and-go steps - Robot arm: joint angles and tip position [Features] - A sheet explaining the formulas and principles of each mechanism - Learn without an internet connection - Dark and light modes - Available in 74 languages - Free, with banner ads only at the bottom of the screen Great for students of mechanical engineering and robotics, anyone curious about how machines work, and teachers looking for classroom material.
