An excellent tutorial from the 1930's on the principles and development of the Differential Gear. Fast Forward to 1:50 if you want to skip the intro.

      Very good video. The way you have explained about the mechanism of axle housing was excellent. I have seen many videos before about the same subject but I couldn't understand how does it work. And here in this video you have explained about the mechanism in a very simple way. Thank you for the information by such a great video.

      It is a one-two punch. The democrats (Obama) took discipline out of schools to edge of insanity, and the republicans (Bush/No Child Left Behind) made it a teach to the test meat grinder where memorizing facts for state tests matters more than critical thinking. Both made it a cash cow system that use student count and test score to funnel revenue into a school.
