You may be wondering who is to blame when your shoelaces come undone. It happens to the best of us. You put the shoe on and you tie the shoelaces as firm as you can. Despite doing so, the shoelaces come undone after a while. Researchers figured out an explanation for this problem.
Mechanical engineers from the University California Berkeley focused on a peculiar problem: shoelaces come undone. They tried to find out why this keeps happening. Researchers observed that it is not the fault of the shoe because it happens to every one of them. The mechanical engineers found that a force is the one that causes this problem.
Your shoelaces come undone when the foot strikes the ground because it creates a force. This movement makes the knot stretch and relax. After that, when we move our foot, the knot unties. Researchers mentioned that this research is not only about shoelaces. They stated that their findings can apply to other structures, like the DNA.
In order to conduct this study, researchers performed a series of experiments. They used a slow-motion camera to record every little detail. Researchers observed that shoelaces come undone in a few seconds despite the fact that they are triggered by a complex interaction of forces.
One of the co-authors of the study was the ones that ran on the treadmill. The other researchers filmed her and observed that movement of the shoelace. Despite the fact that it might seem like an unimportant subject for a research, scientists mentioned that they want to take this study further.
“When you talk about knotted structures, if you can start to understand the shoelace, then you can apply it to other things, like DNA or microstructures, that fail under dynamic forces,” mentioned Christopher Daily-Diamond, leader of the study.
The scientists said that they want to find out more about other types of knotted structures. They want to see if their findings apply to more important knots like the DNA structure. It is interesting to see how researchers can go from “shoelaces come undone” to applying the same theory to the DNA structure. We’ll just have to wait and see what they discover.
What is your opinion about this study? Do you think that they can apply these findings to DNA structures?
