What happens here

The creator contrasts the circular design with square and triangular shapes. He demonstrates that a square wooden insert can fall through its square hole if tilted, and a triangular insert can similarly fall through its triangular hole if not aligned perfectly. This highlights the vulnerability of non-circular shapes to accidental dislodgement.

Goal: Illustrate the disadvantages of non-circular shapes for covers.

Tools and materials

  • Wooden Board with Cutouts — Demonstrating geometric shapes and their properties
  • Wooden Square Insert — Demonstrating the properties of a square shape
  • Wooden Triangular Insert — Demonstrating the properties of a triangular shape

What they say

Hide

seals perfectly every time, no matter how you orient it. Also, structural wise, I'll get into more into that. A square can fall through the hole. Just like that. You have to make sure that you line it up perfectly every time. As well as with a triangle. Triangle falls through the hole. And you have to make sure that you line it up perfectly every time. When force is applied to the square, the stress concentrates in the corners.
