Here is a contraption. let the surfaces be frictionless. a. what must be the ratio of the masses as a function of r? b. if the mass m is 1 m from the center and the angular velocity is 1 rad/s, what must the mass ratio be? let’s say there is friction between the mass m and the horizontal surface with a coefficient of static friction of 0.30. c. what range of angular velocity will allow the masses to not move? consider the two conditions minimum and maximum velocity carefully and separately.
