For the weight of the luggage it's great. For homeschooling, this is fantastic. This physicist-turned-rancher volunteered to be an instructor at a local school on a field trip. Mechanical Advantage is the name of ranch game. The ranch is the perfect laboratory for little fence builders and movers. Living close to cattle and cars makes applicability practical. Children know levers and vectors and can adequately assess cause and effect of efficient mass movement. This load cell is a system measuring device for quantifying and then planning structures sufficient to perform the task. I plan to use this load cell to demonstrate how a pulley and lever work. The cell can be used to practically demonstrate force as a function of mass and acceleration. After playing around with it a bit, I discovered the amazing aspect that so much value can be gained at such a low cost.
