Hi,

I am doing a high power rocket and i have to determine the best material for my fins.

I was wondering if there was a way to ''calculate'' the best materials for my fins? In terms of aerodynamics and strenght? Like only in carbon fiber, or plywood/carbon fiber, fiberglass/carbon fiber, etc.. I know that for strength I can use the modulus of elasticity or the shear modulus, but should I use the rule of mixture to determine it?

Also, i don't know how to evaluate the best material for its aerodynamics caracteristic. I know I have to calculate the drag to find the optimal shape of the fins. However, I cannot find a way to proceed without doing a wind tunnel test.

Thanks a lot for the help,

ask a memetic engineer undergrad anything

If p(3x) = x^2 and p(2x) = x, is it possible that p is a linear function from the
polynomials to the polynomials? Explain your answer. (Hint: Fractions are scalors too!!)

Why don't broken things go back together? It's still glass, so why can't you put it back?

Can you visualized higher-dimensional objects, /sci/?

Why don't you own a study cube?

Don't you want to get into a top-ranked grad school?

Does anyone here have experience with Geography/GIS work? What's it like?

Students at the University of Hull have created MolCraft, a Minecraft world which teaches biochemistry to kids.
It will be free to download and will be available in the MinecraftEdu library for teachers. The funding came from the Royal Society of Chemistry. The creators hope to see it used in schools.

>MolCraft is a world where the majestic helices of myoglobin rise above you. Where you can explore this massive molecule and its iron centre that carries oxygen around your muscles. Or, if you prefer you can fly down a pore through which water molecules normally flow across cell membranes.
>In MolCraft, anyone can explore the building blocks of these incredible natural nano-machines. You can discover how just 20 chemical building blocks can result in the astonishing diversity of structures and functions that are required to hold living things together.”

In 2013 Google, MinecraftEdu and Caltech's Institute for Quantum Information and Matter created qCraft to teach quantum computing to children.

Do you think you'd stand a better chance of learning quantum computing, biochemistry, or whatever, as a child, with a traditional good teacher and a pen and paper, or via minecraft/quirky modern methods?

Any medfags? I touch an unplugged plug and got a static shock from it now my arms tingly. Am I gonna die or am I raiden now? pic unrelated
