Why triangles are strong

Take a moment to ponder the triangle. You must be logged in to post a comment. When a force is applied to a triangle comprised of rigid members with hinged corners there is no movement. A similarly constructed 4 sided polygon a square in this case movement is easily achieved as shown by the dotted lines.

The hexagonal object at the left can be easily deformed. The same hexagonal object with the addition of triangular gussets becomes a virtual triangle as connecting members are rigidized by the triangular gussets. This pier uses nearly uncountable triangles to achieve strength.

At first glance the strength of triangles is not immediately evident. A closer look will reveal that the strength of the structure is achieved by using a myriad of small triangles! Why Are Triangles so Strong? More From Reference. What Is Volume in Science? How Many Men Are in the World? What Is the Lion's Niche? From Wimbledon to the U. Due to triangles ability to withstand tremendous pressure, this shape is often found in architecture to provide stability. Geometry and architecture are linked fundamentally, and by understanding the form of the triangle, architects provide the support they need to a developing structure.

A-frame homes, truss bridges, and geodesic domes rely on triangles to create a durable structure. The smallest polygon is the strongest polygon, and the number of structures relying on the strength of the triangle prove that. As an amateur architect, you can create vast structures using triangles. Triangles are one amazing shape! You can test the strength of a triangle today by building your own truss bridge! Equilateral triangle, and from the middle of each side, one were to place an interior frame board, spanning from each center of the exterior sides to the next, so that now, the triangle has is segmented into four triangles.
