Problem A15: In the figure below, a circular solid disk is leaning up against a step. The radius of the disk is r=n1d. The height of the step is h=n2d. A force of magnitude F is applied to a rope that is attached to the top of the disk. The rope pulls horizontally. The disk has a weight W. What is the maximum force that can be applied such that the disk is in static equilibrium as shown in the figure. If the maximum force is F=W/ √ n3 , what is n3?

n1 = n2 = Input n3:
