About this 3D model
This is a device used for testing middle school students' structures. It is an improvement on putting a structure across two sawhorses and hanging weights from the structure! I've used it for "Jinx Wood" bridge structures as well as sheet metal structures. Check out my TeacherHann YouTube Channel - www.youtube.com/teacherhann - for videos of my students projects being tested to destruction! Kudos to my colleague, fellow middle school Design and Technology teacher Gord McGill for allowing me to replicate his idea!
