In the ten years that have transpired, you probably finished your undergraduate education, your PhD in math, and have invested in your first taxi.

Most, it would seem, have weak understanding of simple ratios and leverage..

More geometry and engineering than Calculus. But, still a good topic.

With bikes, leverage is only half the story. So, one might think that say a 180mm crankset was better than a 165mm crankset. And, yes, it does give good leverage, but one also has a longer pedal stroke, and typically a slower cadence.

& brakes ? MA involves leverage..

derailleur design.. motion for cable pull .. how long things are relative to other things..




etc..

Given that triggerhappy403 resurrected this 10 yo thread with his first post, I wonder if this is a new (or new to me) way of trolling. Have a bot go in to a forum, find the oldest threads and resurrect them with a

yes??

In any case, I think that the OP had a calculus project. And you can get a lot of info out of geometry, but to do stability analysis and such requires one to start with differential and conservation of momentum equations. You try to boil it down ("does the denominator of the transfer function for motion to the side have left half plane zeros" and such).

That's pretty good. Some points deducted for it being the resurrector's first post (search function still works!) but some added back on as the OP has not been here for 3,577 days, for an overall B+ effort.


So close to 10 years!

Did you hear the "Reply All" podcast about the troll-bot who orders a single bottle of Coke from Domino's? It's really surprising how these nefarious troll-bots can wreak havoc with on-line businesses.
