Triangles are the strongest shape because any added force is evenly spread through all three sides. Look closely at the pyramid – it’s made of triangles! Squares or cubes can be strengthened by adding a diagonal piece across the middle, making it two triangles linked together.
The aim of this experiment is to make a triangular and a square structure to test their strengths and then to show the process of construction of a simple truss bridge using a set of beams connected to form a series of triangular structures.
- Highlights the characteristics of various geometric shapes
- Makes the students aware about the various structural components of a bridge.
- Correlation between theory and practical becomes easier
