why triangles are the strongest shape for design
In: Physics
Places where two long items join are typically weak spots due to leverage. Try holding two pencils ends together at a ninety degree angle with your hands. Someone pushing on the other end doesn’t need much force at all to change that angle despite your strength because they are gaining tremendous leverage by pushing against the far end of the pencil.
A triangle makes that far end impossible to move. Thus the whole shape doesn’t change.
