How Do You Make A Bridge Out Of Balsa Wood?
Building a bridge from balsa wood is such a popular educational activity that there are competitive contests for building model bridges. A balsa wood bridge-building project touches on principles of building and construction trades, engineering, physics and static equilibrium. The main goal of building a balsa wood bridge is to construct a bridge that withstands the greatest amount of force before falling. Competition balsa wood bridges have been constructed that hold up to stresses greater than 400 lbs. Sketch out a rough design for your bridge on paper. These sketches will help you develop different ideas of bridge design before you begin to cut your balsa wood. Your design should have a superstructure and a substructure. This view does not have to be to scale, since it is only a rough design. One style of bridge that many designers use is the Warren truss style, which is favored by railroads for its load-bearing capabilities. Sketch a three-view sketch, which will include views of y
