The Roman Arch
Purpose:To investigate the construction of a particular form of architecture, i.e., the Roman Arch.
Procedure:The blocks are numbered according to position and order so the arch can be constructed in front of the class and then tested for strength. A detailed force-vector matrix analysis can be done to see how the arch grows stronger as more force is applied to it (up to an upper limit, of course). Discuss the need for thorough study before building any structure that will be subject to stresses and strains.
