NEW!!! MORE ABOUT BRIDGES!
Mr. Plater sure knows bridges!! We learned that we need extra support bars that are triangular in shape (because, triangles are the strongest shape for bridge support), that the center of the truss bridge is the weakest, and how compression, tension, and torque are three forces that affect how much a bridge can hold.
Here is a place that you can write about all you now know about bridges, and ideas you have for our own bridge design!
