A block of weight W rests on a rough horizontal surface (μs, μk). A rope attached to the block passes over a rough cylindrical peg (friction coefficient μ′, contact angle β) and supports a hanging weight Q. The system is in static equilibrium. If the hanging weight Q is slowly increased until motion is impending, which inequality correctly describes the impending-motion condition, assuming the block tends to slide toward the peg?
