Machine Elements 3D vs Nooodle

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/
