Mrs. Patti Robertsí QUEST students in grades 2-6 at TAC and FAC gained knowledge about bridges around the world as they researched and built models of these bridge types: Roman Arch, Truss, and Suspension. They learned what forces make the different types of bridges work.

Types of bridges:
Beam, or Girder; Truss; Arch; Cantilever; Cable-Stayed, Suspension.

Compression, Tension, Shear, Torsion, Wood, Stone, Brick, Concrete, Reinforced Concrete, Iron, Steel, Steel Cable, Flange, Web, I-Beam Girder, I-beams, gussets, dead weight, overhang, riverward piers, anchor piers, suspended span, Aesthetics

A triangle is the strongest of all two-dimensional geometric shapes, giving a tremendous strength-to-weight ratio. Truss bridges make great use of triangles.
