These cables are capable of withstanding tension but offer no resistance to compression. This kit is part of a series of three plywood bridge kits. Description Are you interested in engineering?

Resonance is the same force that can shatter a glass when exposed to sound vibrations from an opera singers voice. Most of the weight or load of the bridge is transferred by the cables to the anchorage systems. Rope bridges Rope bridges can be dangerous to build and use.

My passion is creating and sharing what I am learning with others. Eventually on November 7, , only four months after it was built the bridge collapsed in a wind of 42 mph.
