Sagging Span

Web span component including sag due to gravity

Summary Variables

	Description
	The Sagging Span component models a span in which the effect of gravity is considered. This components uses a discretization approach to account for the distributed mass of the span. Due to the added model complexity, the Sagging Span component should only be used where the span sag is significant.

	Usage
	The Sagging Span component must be used only as a connector between rollers, drums, a source, or a sink, from the Web Handling Library.
