2.25. Rope between inclines **
A rope rests on two platforms that are both inclined at an angle (which
you are free to pick), as shown in Fig. 2.30. The rope has uniform mass
density, and the coefficient of friction between it and the platforms is 1.
The system has left-right symmetry. What is the largest possible fraction
of the rope that does not touch the platforms? What angle allows this
maximum fraction?
