We have so much material to cover in our beginning manufacturing and engineering class that we don’t get very in depth their first year. It is mostly an introduction and some hands on experience, practice and then move on. This is true for our Arduino unit. This is most students first experience with electronics and coding, so we start simple.
This is not a how to use the Arduino, but rather a how I teach Arduino.
Truss Bridge Unit
We just started our Bridge Unit. I will explain the rules and deadlines for students to refer to. I am going to also add some links for help.
weight limit of the bridge: 200 grams
span needed to cross: 30 inches
Any material is allowed except pre-hardened glue or contained gases
The bridge must hold a 3in x 5in piece of wood that has an eyebolt and a carabiner attached. This “car” must be placed within 3in of the center of the bridge.
The bridge is due and should be ready for testing on Friday, May 1. We will test the bridges the following Monday.
The bridge goal for weight prior to breaking 77 pounds.
The record so far is 121 pounds.
