What happens here

Using the wooden triangle frame, the presenter explains the concepts of compression and tension. When downward forces are applied to the top of the triangle, the top members are under 'compression' (being pushed together), while the bottom member experiences 'tension' (being pulled apart). He points out that the fasteners (nails) at the base are crucial in resisting this tension and preventing the triangle from spreading apart, maintaining its structural integrity.

Goal: Illustrate how forces (compression and tension) are distributed and resisted within a triangular structure.

Tools and materials

  • Nails — Representing fasteners that resist tension at the base
  • Wooden Triangle Frame N/A — To demonstrate compression and tension

What they say

Hide

Your house is made of two shapes. You have squares for your walls and triangles for your roof. Squares are weak and triangles are very strong. When downward forces are applied, the top is in compression and the bottom is in tension. So, these fasteners is all that holds this structure from spreading apart. So, to keep a house from falling over, we need to add more triangles. As a house is built, it'll get diagonal bracing. This is to help with shear
