In the simple triangular roof truss the load of the pitched roof is supported partly by the sustaining walls and partly by the pull of the horizontal element between the two walls. In the fan truss shown, the same priciple of dividing loads into thrusting and pulling elements is used in order to give better distributionof thrust over the supported area Reduction of the weights and forces on individual members, that cause distortion and deformation can permit the use of less expensive or thinner materials reducing costs.
A truss is designed and engineered to distribute the weight which it carries over a broader area by adding additional supporting structure. This allows the truss to carry more weight or be built from a smaller material.

It is dependent on where you live, but roof trusses are available to purchase and be delivered to your house. Or you could pick up the trusses yourself if you prefer those means.
A lot.

For a gable end to gable end installation on 16" spacing you would need 34 trusses, 2 of which would be the gables. If your roof-line has hip ends or will be incorporated into an existing structure there will be more trusses.
Busses rhymes with trusses. Let's use the word in a sentence: Since Mitch Longley didn't have a car, he was forced to take the busses.
Roof trusses are used to support the roof and to make certain that the weight of the roof is distributed equally across the building for maximum support.
