1. How are trusses able to span large distances?
Trusses are able to span large distances by the use of triangles to distribute the weight evenly to make sure the truss is stable
2. What do I have to understand in order to use mathematics to predict truss strength?
When trying to calculate the strength of a truss you must know how to use trigonometry and also some knowledge of how forces work on different beams and
supports.
3. How are different roof styles and pitches related to different architectural styles?
One architectual style, cubic, has low pitched roofs which requires different trusses/supports than a victorian home.
4. What is the effect of different materials on the strength of a rafter or a truss?
Some materials are stronger and will make your truss more stable, but the stronger materials tend to be heavier and require more support to remain stable
