Problem:
"Two blocks of equal masses m are attached by an ideal string. One mass lies at radial distance r from the center of a horizontal turntable rotating with constant angular speed of 6 rad/s, while the second hangs from the string inside the hollow spindle of the turntable.The coefficient of static friction between the surface of the turntable and the mass lying on it is 0.5. Find the maximum and minimum values of r such that the mass lying on the turntable does not slide."
My initial idea was
Tm - (Ffriction + Fcentrifugal) = 0
and then I would get the zeroes of the function, but it feels like I'm really wrong about this. Can anyone explain how to solve this?
