  1. Electric motors produce maximum torque at zero rpm.
  2. Please, take a few minutes and read Lizzie Velasquez's story: http://www.bbc.com/news/blogs-ouch-30948179 Excerpt: "She was 17 when she stumbled across a YouTube video entitled "The World's Ugliest Woman"."
  3. At 14 years old, using mostly scrap materials, William Kamkwamba built a wind turbine to power his family's home.
  4. Throughout your term of employment you retain the right to choose to work there. A slave has no such choice.
  5. Start here: http://www.backyardmetalcasting.com/index.html
  6. There is a wide variety of GPS modules and devices available for DIYers. Take a look at Hack-a-Day for some ideas. Some retailers: https://www.sparkfun.com/search/results?term=gps&what=products http://www.seeedstudio.com/depot/index.php?main_page=advanced_search_result&search_in_description=0&keyword=gps
  7. Actually, "bevel up" planes work very well. http://www.google.com/search?q=bevel-up+plane
  8. You might start by looking at what's in existing products -- Lacquer Thinner MSDS
  9. Yes, but your question is ambiguous. Hydraulic systems can use delay valves, so I guess you could consider that a "device" for imparting hysteresis. (Undesired hysteresis is actually a common problem in hydraulics.) Mechanical systems would have it built into the design of the mechanism.
  10. Some well written definitions: http://www.webopedia.com/TERM/O/operating_system.html http://en.wikipedia.org/wiki/Operating_system http://www.webopedia.com/TERM/N/network.html http://en.wikipedia.org/wiki/Computer_network
  11. Many people here will be quite happy to help if you show that you are at least trying to do your own work, but do not expect to be spoon-fed answers to your homework.
  12. Let me see if I can simplify this, from the perspective of someone with no formal scientific education. Fred, using Newtonian physics, calculates the impact force of an apple striking the ground after falling from a tree. Jack measures various parameters of an actual apple, falling from an actual tree. He records the results from dozens of apples. Lisa compares Fred's math with Jack's measurements. The data sets match within acceptable margins of error. (For example, calibration factors within the measurement instrumentation; wind causing some of the apples to fall in a slightly different trajectory.) Conclusion: The theory behind Newton's laws, for the purposes of apples falling from trees here on Earth, is demonstrated to be valid. For an alternate hypothesis/theory to be accepted, it must also be able to mathematically predict similar results for those same apples falling from those same trees. If the new hypothesis can not correctly make these predictions, then how can you trust it to be accurate about anything else?
  13. Modern automatic transmissions are highly integrated into the vehicle's electronics.
  14. I believe there are some deep-dwelling ocean creatures with rudimentary light-sensing organs.
  15. Is the class, "Introduction to Programming", or "Introduction to Programming C#"? If you have no previous coding experience, then you should be learning about basic principals of programming and machine architecture.
