1. The coefficient of static friction between the surface of the rotating cylinder of radius and the block of mass shown below is . Find the minimum rotational speed (in and rev/s) that would prevent the block from sliding down.
Expert Answer
Ans. In the figure below the force of friction Fs acts in the vertically upward direction. The weight (mg) of the block acts in the vertically downwa
