How To Build Balsa Wood Model Truss Bridges

Following you will know more about the Balsa wood. 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 grid square represents a /-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're distributed.
Building
Measure out the outer structure of the bridge on balsa wood, and draw out the pieces on the wood. Mark the pieces using the permanent marker.
Cut out the frame, using the scissors or knife to separate the pieces.
Glue the pieces together and leave them to dry for a few minutes. You can use masking tape nvnwzhiq to keep the pieces stuck together until dry.
Measure out the truss pieces and cut them out of the balsa stock.
Glue the pieces into place according to your diagram. Again, you can use masking tape to strengthen the connection. Leave the design to dry overnight.
