A small object A of mass m = 0.21 kg is held against the vertical side of the rotating cylindrical container of radius r = 0.41 m by centrifugal action. If the coefficient of static friction between the object and the container is μ = 0.61, determine the minimum rotational rate 0 = w of the container which will keep the object from slipping down the vertical side. b=0 Answer: W= i A rad/s
