Dynamometer

The UGEARS Dynamometer is one of the simplest UGEARS models, and a playful one. Like the UGEARS Pneumatic Engine, it turns air pressure into motion: blow on the top gear and the mechanism spins an arrow that lands on your task for the day. Small as it is, it shows several basic principles of mechanics at work.

Key features

• Powered by your breath: blow on the top gear
• Spinning arrow picks a task for the day
• Shows a cascade of gears in motion
• Demonstrates the Geneva drive, a classic mechanical junction
• One of the simplest models in the UGEARS range
