Thank you. The coupled variant was also very cool !

Is this some esoteric aspect of Physics, that few ever see, or is this part of the common core that almost every Physics major sees? http://scienceworld.wolfram.com/physics/DoublePendulum.html

You have 2 bikes. They only differ in 1 way. The length of the crank arm (where pedal attaches) https://en.wikipedia.org/wiki/Crankset How will these bikes differ when riding? Is one harder to pedal than the other? Why?

mmeftahpour, thanks for the Word doc. That also has a small description of the acceleration data.

Nothing mathematical there, but did mention about the concept of deceleration. Because airbag sensors measure deceleration, vehicle speed is not a good indicator of whether an airbag should have deployed. Airbags can deploy due to the vehicle's undercarriage striking a low object protruding...

Anyone care to verify my basic thought process?

Pretty sure it's not a sensor in the bumper, but a computer algorithm that monitors speed. This sounds right. Is there any way to describe what the algorithm is looking for? ACU is fed constant speed values from speedometer. ACU can calculate acceleration based on time elapsed b/w 2 speed...

Today, I am an adult who is re-learning some Calculus. But, I ask a lot of questions about anything and everything. Has anyone ever explored the concepts and/or Calculus/Physics behind auto airbag deployment? Computer feeds real time velocity points and the ECU is monitoring for a sudden...
