If I were riding a bicycle over an obstacle, I'd first shift my weight back to pull the front wheel up. Do you want to account for this in your model? Perhaps the easiest version of your problem uses a totally inelastic collision of a wheel with a log with no slipping. Then you only need to calculate the energy loss in the beginning and the end of the interaction. | |

Maybe the PO.net people haven't realized this was necessary. Also, the first several real questions were asked by moderators, i.e., one reason why they joined the site was because they had questions. Incidentally, there is a physicsoverflow.com that has slightly more activity. | |
| Jun 12, 2010 at 10:32 | comment | added | TonyK | 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. | |

| Jun 12, 2010 at 6:27 | comment | added | Robin Chapman | As you say in your tag, this is really a physics question, not a mathematical one. | |
