Abstract
The purpose of this project is to design a safe bridge tester system that is able to measure the strength and endurance of bridges under pressure in pounds per square inch. Through the engineering 215 class at Humboldt state University, students from team Burke der Meister designed a bridge tester machine that will be integrated into the engineering section of the STEAM Program at Zane Middle school for projects and competitions.
