What is the optimal format for posting physics problems on a forum?
AI Thread Summary
The optimal format for posting physics problems on a forum includes using typed text, preferably with LaTeX, to enhance clarity and readability. Posting images that are misaligned or handwritten can significantly reduce the likelihood of receiving responses. It is advisable to avoid plugging in numbers before completing the final algebraic steps, as this can confuse readers. Clear and well-structured posts are more likely to engage the community and elicit helpful responses. Following these guidelines can improve the chances of getting assistance with physics problems.
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question.
Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point?
Lets call the point which connects the string and rod as P.
Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is
The second part of the problem is exactly why you get this affect.
And one more spoiler:
F1=(5000+200)g=5200*10=52000N --> F2=(5000+100)g=5100*10=51000N ?
