Final Project!
Because
neither an arch, truss or cable-stay design can span the distance (with an
opening in the middle), the final
bridge
is a combination of an arching-cantilever and a cable-stay bridge. the pulley
system aand the structure that
supports
it is a clear representation of the toilet bowl flushing mechanism. the systems
come together where the
drawbridge
breaks the bridge and is supported by the cantilever, and the cable-stay is the
support for the remainder
of
the span. as an additive, the placement of the platform helps to counterweigh
the weight of the cantilever.
