 I'm sure FIRST did the math. They always do the math. Just not math humans use. It was probably given to them from NASA from the aliens so we'd quit predicting the divisions before they release it. - Koko Ed [more] |

Re: To clarify polycarbonate (minibots)
In general, polycarbonate is roughly half the density of aluminum. But it's modulus of elasticity is much lower, so to make a part as rigid as aluminum it needs to be more than twice as thick.
If you can make angles or channels from polycarbonate, you can make a light, rigid structure. It's not easy to bend it a full 90 degrees though. You can bend it with a brake, and adding heat from a heat gun helps, but still it's not easy to do it. |
