Wooden Truss 3D


 Model Description This 3D model of a bridge is a model that is very close to a real representation of a bridge. It has a number of realistic features that cannot be shown with K’NEX or other simple structures.  This demonstration should take 15-20 minutes. Engineering Principle Bridges are more than just trusses put together. […]

Wooden Truss 2D


 Model Description This is a simple demonstration to introduce the basic principles of truss behavior and analysis. It will show how the shape of a truss—and not necessarily its weight/material—determines its stability. A simple truss design will be used to show that triangles are the important stability shape used in trusses rather than squares or […]
