Triangle Tuesday!

What happens here

Next, introduce a diagonal wooden brace. Position this brace across one of the corners of the previously flexible square frame, effectively dividing the square into two triangular sections. Securely attach the diagonal brace to the opposite corners of the square. Attempt to deform the frame again by applying pressure to the corners. You will observe that the frame is now significantly more rigid and resistant to changing its shape. This illustrates that by creating triangles within the structure, the overall stability and strength are dramatically increased.

Goal: Show how adding a diagonal brace increases the frame's rigidity.

Tools and materials

  • Diagonal Wooden Brace N/A — To add rigidity by creating triangular sections
  • Hammer or Drill N/A — To attach the diagonal brace if using nails or screws
  • Nails or Screws N/A — To secure the diagonal brace
  • Square Wooden Frame N/A — The base structure to be modified

What they say

Hide

the corners. Because a square can change shape by rotating on the corners. That's why it's not very rigid. But let's add one board in here and change that. Now, just by adding one board, we created two triangles. Now, if this shape wants to move like it did before, this diagonal has to get longer or shorter. And wood doesn't like stretching or shrinking. And that's why a triangle is so special. Because a triangle can't change shape unless one of the sides changes length.
