Imagine a bicycle travelling at speed, and then rolling over a log. What are the principles behind calculating the force that is required to roll a wheel over an obstacle?

    $\begingroup$ As you say in your tag, this is really a physics question, not a mathematical one. $\endgroup$ Jun 12, 2010 at 6:27

    $\begingroup$ PhysicsOverflow is physicsoverflow.net . It seems to have just launched and is awaiting its first question. Its FAQ proclaims "No question is too trivial or too "newbie" " (unlike MO :-) ). $\endgroup$ Jun 12, 2010 at 9:28

    $\begingroup$ I just tried to post this question for you at PhysicsOverflow. First I failed because I didn't give the question a tag; then I looked for a suitable tag, and found that there were none defined (i.e. no tags at all, suitable or unsuitable); then I tried to create a tag and it wouldn't let me because I'm a new user. So that explains why PhysicsOverflow has no questions then. $\endgroup$
