WebEveryone above has good engineering advice on truss design. As for building the balsa wood bridge, there are quite a few tricks I learned in actual construction that made the bridge 10x stronger by reinforcing weak points. Lap joints are 100x better than butt joints. Mind including a picture of the materials you get to use? WebStep 2: Step 1: Base. Measure and cut a 14 inch piece of balsa wood and label it the base. (Tip: when cutting balsa wood it has a tendency to fray at the ends leaving an uneven …

WebJun 24, 2024 · Balsa Wood Bridge Design. The opportunity to introduce these two topics presented itself in the bridge design unit where the students were tasked with designing and building their own balsa wood bridges. The goal of this unit is to use engineering principles to construct a bridge that can withstand the greatest weight before it fails. Webtruss bridge can hold an average amount of weight, and the beam bridge could hold the least amount of weight. This experiment tested the arch, deck truss, and beam bridges to see which could hold the heaviest amount of weight. My mother helped copy edit my essay and cut some pieces of wood during the construction process of my bridges. phipps mckinnon building edmonton

WebBalsa wood sticks can be used for towers, bridges, structures, craft projects, RC airplanes, and models. Balsa has a high weight to strength ratio and can be very light weight. Balsa can vary between 3# (foam weight) - 40# (oak weight) for pounds per cubic foot (lbs/cuft) but the most common densities are 8-16 pounds per cubic foot.
