What We're Doing: Building Bridges
Posted 05/22/2014 04:02PM
Mr. Turner's two Advanced Geometry classes built a suspension bridge using a Makerbot 3-D printer. After studying three-dimensional shapes, the class used Google Sketchup to design four 12" bridge towers and seven girders to support the roadbed.
Both classes worked in small groups to craft and manufacture the key components of the bridge and overcame several different design flaws throughout the process. On Thursday, the final day of class, students in B period tied kevlar string to the girders and removed the support material to reveal a working suspension bridge. The bridge features two HO tracks with two running model engines. Next year's class will work to improve the cost to weight ratio and attempt to temporarily install the bridge over the brook that runs through campus.
