I'm studying wind turbine technology at the moment. I'm stuck on the concept of feathering. It is exploited in order to ensure that a turbine will only go so fast in a high wind. But how does it work?

Am I the only person that finds it odd that someone would make an ARCH bridge where the arch is made out of steel?

The arch in an arch bridge is always under compression, and steel is not that great under compression. I think a small layer of steel reinforced concrete under the steel arches would have made that bridge last forever. There are stone arches that were built over 1000 years ago still standing, but thats because stone and concrete are great under compression. Steel arches are pretty much worthless and give you a false sense of security.

Anyone else feel this way?

I am trying to run a 20 amp circuit 300 feet to a place I need electricity. I already have 12 gauge exterior wire but at this distance, I don't know what kind of amperage it could handle. So can I run two lengths in parallel in order to operate a higher amperage circuit?

Maybe a parallel of about 200 feet with a single run for the remaining 100 feet. Will either of these methods work?

Thank you in advance.
Dave
