Working Principle – Strength and stability of a triangular structure
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 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.
