Warm Up Exercise, December 11 & 12 2018 (with supplement)

SHORT ESSAY:1 Some of the examples given for gears include devices such as mechanical alarm clocks and hand cranked drills.  Would you expect gears to be more or less important now that so many of the devices we use today are either electronic and/or computer controlled?

SUPPLEMENTAL QUESTION: Only do the supplement below if you are one of the three students who have two engineering classes. Otherwise, do not proceed.

If you wanted to take a good look at lots of gears at work, and could open up any machine or devices (without fear of wrecking it), where would you look?  What kind of gears would you expect to find?

  1. Your short essay should be a paragraph or two. “Explain” means to give some logical reasons for your point of view
