Description
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 - 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!

Instructions
It's made of 2x4's nailed together, and the actual testing takes place using some 3/16" cable and a small hydraulic car jack.
I also needed some accessories for the cable (fasteners, etc.), some large bolts and related nuts and washers.
The cable gets wrapped around a large galvinized metal pipe.
Finally, I needed a digital kitchen timer, an ANALOG bathroom scale (digital won't work!) and a ruler.
NOTE: You may need some plywood props to adjust for height under and on top of the scale. I didn't include these in my sketchup file.
Also, we intentionally used nails longer than needed so that we could bend them over when they are sticking out the opposite side. This increases the structure testers structural strength!
