A frictionless pulley attached to a block of mass 11 =100 kg spans a string with a cylinder of mass 22. The coefficient of friction between the inclined surface and the block at an angle θ = 20° is = 0.2. Find the minimum and maximum mass of the cylinder that can maintain equilibrium without the block going down or up along the slope. The frictional force acts opposite to the tangential direction in which the object is about to move and has a maximum value of = when the slide is imminent. N is a normal reaction force.
