What is weakest shape?
If you Google the weakest shape, the most common answer is the circle. Many variables will factor here as well. As it turns out, there really is no simple, one-size-fits-all answer to the question. Knowing if we need strength for support or containment is an example of what needs to be known to answer the question.
What shapes are strongest?
There are several shapes that are used when strength is important. The arc (think: circle) is the strongest structural shape, and in nature, the sphere is the strongest 3-d shape. The reason being is that stress is distributed equally along the arc instead of concentrating at any one point.
What's stronger circle or triangle?
What is stronger, a triangle or a circle? Structurally, a triangle is the strongest shape. A triangle constructed from three rigid rods, can only have one shape. It requires no strength from the joints, and relies solely on the strength of those rods to maintain its shape.
What is the hardest shape to break?
Triangles are the strongest shape there is. Any weight placed on them is evenly distributed on all 3 sides. They represent geometric sturdiness; no matter how much weight you put on any side, it will not break.
