Arches

The video explores the historical and structural significance of arches, pioneered by the Romans, and their role in architecture. It explains how arches distribute forces, making them strong and durable. The evolution of bridge design is discussed, highlighting the shift from semicircular to parabolic arches, which allow for more efficient and flexible structures.

What role did the keystone play in the construction of an arch?

How does the compression of an arch contribute to its strength?

How do the forces acting on an arch differ from those acting on a rectangular beam?

In what ways have modern bridges evolved from Roman arch designs?

What advantages does a parabolic arch design have over a semicircular arch design?
