This is a great little short film that talks about the strength in the shape of a catenary arch. The catenary arch is a representation of the gravity pulling down a length of chain between 2 points, flipped upside down. The geometry of the catenary arch is all around us in our modern construction and considered to be the strongest of all arch shapes. It is also a well recognized shape with the Gateway arch in St. Louis as well as the famous 'golden arches' of McDonalds.
