The author effectively communicates the interactions in the passage by using sequential and cause and effect text structure. This structure helps convey the process of the experiment and illustrates how the actions of walking and running together lead to shoelace knot failure.
"Science: Why Shoelace Knot Failure"
by Nsikan Akpan
Right off the bat, they found shoelaces didn’t untie when a person just swung their foot nor when they only stamped the ground. The combination of the two activities, which define walking and running, appeared responsible.
The team acquired a high-speed camera and pointed it at Gregg’s shoes as she ran on a treadmill. Gregg had tied her laces with one of two knots: square (strong) knot or a granary (weak) knot. Here’s how O’Reilly described the difference between the two:
You tie the laces first. That’s where you loop the strands together, one around the other. Next, you form the “bunny” knots. If you loop the bunny knots together the same direction that you tied the first knot together, that’s a weak knot. But if you do the opposite. Instead of putting one over the other, you switch the order, then you get the strong knot.
What the team noticed in the videos was nothing happened for a long time, and then — all of the sudden — the laces came untied, typically over the course of two strides. It didn’t matter if Gregg had used a strong knot or a weak knot.
Use the passage from “The Science Behind Why Your Shoelace Knot Is Doomed to Fail” by Nsikan Akpan to answer the question.
