Why are triangles the most stable shape in construction/engineering?
In: Engineering
I’ll start with a square. If a square is made from four boards and every corner is a hinge like your elbow, there is a problem. This shape can easily be squished out of shape. Your square can easily be changed into a parallelagram, A triangle cannot. A triangle is said to be inherently rigid because of this. It’s natural, and so we see it all around us.
Sidenote: triangles can’t be bent. Moving any vertex it will always spin around an axis. That’s really useful in 3d modelling.
