Homework Statement
There are two beads at the top of a hoop that is tied by a string. The beads start moving downward on the hoop on each side. M is the hoop's mass and m represents each bead's mass.
What is that mass ratio that will cause the hoop to elevate.
Homework Equations
T>= (M +2m)g
The Attempt at a Solution
I tried to go about this question but I couldn't finish the equations.
I know that the momentum on the x-axis isn't relevant since the beads cancel each other out.
I'm not sure how to use the hoop as a constraint. I can find the difference in potential energy but I can't seem to connect it to the force - only to the momentum.
I would really appreciate the help.
