How does the span of a truss relate to load-carrying capacity and when a truss fails, how much area is involved?

For a deeper material truss, increase in distance between the top chord and bottom chord will cause the truss to bear more load with increase in Span

For Cantilever Truss ; increase in span will result in decrease in load bearing capacity of the truss

When a truss fails the areas that are affected are the supports of the truss and its corresponding spam. i.e. 4 crossbars at quarter of the span

Explanation:

The load-carrying capacity of a truss on the span  is basically based on the type of truss ,

For a deeper material truss, increase in distance between the top chord and bottom chord will cause the truss to bear more load with increase in Span

For Cantilever Truss ; increase in span will result in decrease in load bearing capacity of the truss

When a truss fails the areas that are affected are the supports of the truss and its corresponding spam. i.e. 4 crossbars at quarter of the span
