KIGAKU vs Machine Elements 3D

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.

Machine Elements turns mechanical engineering into a visual, hands-on learning experience. Follow a structured path from forces, materials, and tolerances to shafts, bearings, joints, power transmissions, gear systems, and gearboxes. Each lesson combines concise engineering explanations with purpose-built diagrams, motion, and quick checks. Open interactive 3D assemblies to rotate and zoom mechanisms, select individual parts, hide components, and inspect how real assemblies are built. Explore bearings from the inside, compare gear arrangements, and see how shafts, couplings, belt drives, chain drives, manual transmissions, automatic transmissions, and CVTs transfer motion and load. Features: • Guided learning path with visible lesson progress • Detailed lessons from fundamentals to advanced mechanisms • Animated engineering diagrams • Interactive 3D models with rotation, zoom, selection, and exploded views • Focused quizzes with explanations • English, Russian, Spanish, and Greek interface languages Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
