1. The problem statement, all variables and given/known data Find the required angular velocity of the stick swinging around it's end axis (like a simple pendulum only without the added mass) at the point of "balance" (where the sinus function crosses the x axis I suppose, sorry for the "weird" translation) so that it will be able to make one full rotation. I am given it's length and it's "swing time" for small displacements (getting sin(θ) = θ using the Maclaurin series) 2. Relevant equations 3. The attempt at a solution I have attempted it by setting the potential energy at the above position at full and kinetic at zero, but I am not given a mass for the stick, and I doubt my approach was very sane given the problem.
