Now, experiments with wires have helped scientists develop an equation explaining the forces involved within one of the simplest knots around, the overhand knot. Such work could one day lead to a better idea of what knots work best for given applications, such as the stitches used in surgery and the steel cables used in construction, the researchers said.
"Now we can understand the basic principles underlying overhand knots, which are the most basic type of knots used in our everyday life," said study lead author Khalid Jawed, an engineer at MIT in Cambridge. "This can serve as a starting point to investigate the mechanics of more complex type of knots."
