In this video, we solve a physics Olympiad–style problem about a rope suspended between two inclined planes. The rope has uniform mass distribution and friction coefficient μ = 1. We determine the maximum fraction of the rope that can hang freely without touching the planes and find the critical angle θ that allows this maximum.
We go step by step through:
✔️ Setting up the symmetry and forces on the rope
✔️ Applying equilibrium conditions
✔️ Using friction at the limiting case
✔️ Deriving the relation between suspended fraction f and angle θ
✔️ Maximizing f to find the final result
📌 Topics Covered:
Rope on inclined planes
Static friction and limiting equilibrium
