Why Are Triangles So Strong In Structures

When force is applied on a shape like a rectangle it would flatten out. Triangles are strong because of their inherent structural characteristics.

Triangles are the strongest shape because they have fixed angles and don t distort very easily.

Why are triangles so strong in structures. Out of all the two dimensional shapes we can make out of straight struts of metal only a triangle is rigid. Due to the rigidness of the triangle s shapes high amounts of forces can be sustained without deformation. The strength of triangles also extends to the three dimensional world.

All other polygons shapes made out of straight line pieces connected at the end to form a circuit are not rigid. Therefore in order to change a triangle s shape an edge must collapse. The corner angles of a triangle cannot change without an accompanying change in the length of the edge.

Therefore in order to change a triangle s shape an edge must collapse. The corner angles of a triangle cannot change without an accompanying change in the length of the edge. Triangles are often used as trusses in bridges or other support structures in buildings.

The diagonal board creates triangles which adds support to the gate. Engineers and architects go to great lengths to ensure both that structures will be able to serve their intended function and that they will be stable. The same hexagonal object with the addition of triangular gussets becomes a virtual triangle as connecting members are rigidized by the triangular gussets.

Triangles are strong because of their inherent structural characteristics. Triangles are used in bridges because they evenly distribute weight without changing their proportions. Triangles are special because they are exceptionally strong.

Edges can be made much stronger than connections. All other shapes can be deformed with a simple push if the shape is hinged at the corners for example a rectangle can be pushed over into a parallelogram. For a triangle no matter what type this can t happen.

This is why you see triangles all over the place in the world around you. The shape of buildings and other structures are usually no accident. They can easily be fit together to provide strength and stability over a wide area.

Much of that durability results from the characteristics of triangles which are the superheroes of shapes. Michael busnick owner of american ingenuity which sells dome homes says triangles are key to making domes strong. Edges can be made much stronger than connections.

A pyramid comprised of four triangles is the three dimensional analog of the triangle in the two dimensional world. Before triangles were used in bridges they were weak and could not be very big. That s a very special property to have.
