Make Your Own Bridge

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.

Learning Outcomes

1. Highlights the characteristics of various geometric shapes
2. Makes the students aware about the various structural components of a bridge.
3. Correlation between theory and practical becomes easier
