1. The problem statement, all variables and given/known data The question is number 12 on this practice exam: http://www.eastwoodzhao.com/exams/2003 - 2005/Exams/Physics/August 2003.pdf 2. Relevant equations Well, torque = force x distance I don't even think you need that though, I think it's a matter of the net force acting on the stick. 3. The attempt at a solution I honestly have no idea with F just being a variable! Thanks! Sorry I wasn't more helpful!
