A bartender places a cubic ice cube with side length a=2.0cm on the rim of a cylindrical glass. The ice cube is positioned so that exactly half of its bottom face hangs over the edge of the glass rim, while the other half rests on the rim. The rim has negligible thickness. The ice cube has uniform density ρ=917kg/m3. Find the minimum coefficient of static friction μs between the ice cube and the glass rim that prevents the cube from sliding off the edge.
