Today we say goodbye to our first engineer – I’m sorry to say that RACHEL is now out of the competition (though we hope they’ll still join us for chats and answer some more questions in Ask!).
Did you know…
- Triangles are stronger than squares:
cmcgrath : Why are triangular shapes so stable?
nicolalazenby : Triangles are so strong because the way they react to forces, a square for example can just get pushed over as when you push the top corner there is nothing to stop the frame from moving. a triangle however, if you push the point at the top, the side of the frame will pull it back whilst the other side of the frame will push it back….. I hope that makes sense!!
