There are many different types of arches found in architecture, but what distinguishes the Roman arch from all the rest is that the blocks are designed to uniformly distribute the weight downward and outward throughout all the blocks that make up the arch. In other words, like a sphere, there is no point along the arch that is weaker than another. This actually makes it one of the strongest structural design concepts known to man. This kit allows a teacher to build their own Roman arch for teaching static equilibrium and practical math applications. Highly recommended for the physics or math classroom setting!
