Engineering - August 2007

Honeybees routinely build honeycombs, these possessing striking geometric features.

Honeycomb panels - especially Aluminum - are routinely used in Aerospace. They have an incredible strength-to-weight ratio.

Googling gave me little more. So, I wonder if there's a relationship between the honeycomb panels so often used in aircraft and the honeycombs built by bees. Thanks!

This question is regarding the appliances certified by ENERGY STAR. Even if they are turned off but they are plugged to the electrical source, do they still continue to use up electricity, if they do is it same compared to when they are turned on and under full use?

I've heard every opinion from people of various qualifications including it doesn't matter, only when it's ~99% dead, if you let it die completely it'll never hold the same maximum charge. Perhaps the answer is different for different types of batteries.

WHAT WOULD YOU DO IF YOU LEARNED THAT ALMOST
EVERYTHING YOU HAVE BEEN TOLD ABOUT MUSLIM
TERRORISM OVER THE LAST 6 YEARS, WERE ALL LIES?

Why don't you do your own independent research to find out
the REAL truth?

You have been told to fight in a war on terror - this is a LIFE &
DEATH MATTER! Don't you owe it to yourself, to check that
what you are being told is really 100% correct, 100% true,
100% accurate and consistent with the real FACTS? (and not
just some neo-con war monger's opinion?)

FACTS:

Melting point of steel = 1532 C
(molten steel was filmed dripping out of the South Tower)

Jet fuel fire temperature in still air = 233-250 C
(use a pyrometer for proof)

I am a senior at the university of toledo and im pretty close to graduating. This past summer semester i had a laboratory class involving mechanics of materials and mechanical vibrations. I had took my vibrations class in summer of 2006 and did ok in it, but after taking the lab class, i realized that the teacher did not teach us anything useful. I was the only one in the class that didnt have a clue what was going on. I mean i had no idea what mode shapes were and how to solve problems involving them.

After taking this lab class and barely getting through with the vibrations part of it, ive started thinking that maybe i should go back and take the class again with a teacher that i know teaches the class well.

My question is, in your opinion, would this be a good idea, or a waste of time? I dont think i want to do design work when i finish school, nor do i want to do research and development. I kinda think i want to go into manufacturing or process engineering.

I have 2p& (C5), 3n3 332 (C4), 10n 103 (C3), 22n 223 (C2), and 22p (C6) ceramic capacitors for an FM transmitter. How do i tell which sides are positive/negative?

There are no markings on them. Both leads are the same length.

The only markings are the label of the capacitor and there are some with black on the tips of the capacitor.

Does it matter if I place them turned the opposite way?

Thanks.

Ok, me and my friend developed a prototype for a Hydrogen engine. We are pretty confident it will work, but we are having trouble getting pure hydrogen. we are using electrolysis, but we cant get the hydrogen inside an enclosed container. Basically, we need help harvesting hydrogen.

Why do they always run a hot, common and ground for an electrical circuit when you can get a complete circuit just using the hot and a good grounding rod driven into the ground. This seams redundant and wasteful. Running three copper wires instead sure uses a lot more copper than just one wire with a ground. I take it there are things going on here that I do not understand.
Thanks in advance.

I'm trying to find out which oil to use in an air compressor.

The air pump recommends "air compressor oil", but it is being used in the food industry, and I need to know name/brand of a good food grade oil for this purpose. Thanks.
