How Do You Use Balsa Wood In Building Model Truss Bridges?
The truss bridge is one of the strongest designs for bridges because it effectively balances out the various tensions and forces acting on the bridge. Building a model truss bridge out of balsa wood is actually fairly simple, as long as you understand how the design of a truss bridge works. The reason balsa makes such a good material for this kind of project is that it’s the strongest material available compared with its weight. Research the design of a truss bridge. Search for truss bridge images on the web, or consult websites to better understand how a truss bridge looks and functions. Draw a scale image of the truss bridge on your grid paper. The scale will help you when designing, so use something simple like 1 grid square represents a 1/8-inch square. Start by drawing the outline of the bridge, then add some support beams to the structure. Consider how the bridge will react when forces are placed on it. Draw some arrows or use an application to represent the forces and how they’r
