Discover how engineers and scientists measure force by building and calibrating your own LEGO® Technic Newton Meter.
Using springs, gears and a custom scale, you’ll construct a working force meter capable of measuring loads and investigating one of the most important relationships in physics: Hooke’s Law.
Difficulty: ★★☆
Approx build time: 30 minutes
Topics: Forces, Mass, Hooke’s Law, Measurement, Calibration, Gear Ratios
This build uses springs or elastic bands to resist a pulling force. Interchangable gears are used to convert linear motion to the rotation of a dial, letting you calibrate the measurements for different spring strengths. Pre-set sticker PDFs and Inkscape files are available for free download and full instructions on how to design your own are included in the lesson pack.
