Observation Deck Project ENB110 – Engineering Statics and Materials

Executive Summary

As requested by Black Suit Infrastructure Inc this report evaluates a possible design of a proposed observation deck at Mount Tamborine through a 1:100 scale model. It is required to be used for general sightseeing, and also for extreme sports such as bungee jumping, BASE jumping and hang-­‐glider launching.

In particular the report highlights:

•
Current
related bridge structures already in use •
Methods
of materials testing •
Materials
and design research and selection •
The
related costs, dimensions and load capacity of the bridge

It was decided that balsa wood and a Pratt truss would be the most appropriate materials and design to use for this application. This was due to both materials being strong, effective and cheap, allowing the raw materials cost to remain low while also preventing over engineering. This is a reasonable result for a light prototype bridge which only weighs approximately 150g.
