Chapt. 5Newton’s Laws and Dynamics I6114. An ideal rope (i.e., massless, but it has friction so the monkey can grip it) hangs over ideal treebough (i.e., frictionless). The parts on both sides hang vertically. A block of 10 kg sits on theground is tied to one end of the rope. An ideal monkey of mass 5 kg climbs up the rope on theopposite side of the bough from the block.NOTE:How the monkey is supported and can be accelerated is a somewhat difficult tounderstand.She exerts a friction force on a rope segment that is equal and opposite to thefriction force of the rope segment on her needed to support her against gravity and accelerateher. The rope segment isn’t moving at all, and so the monkey’s force on the segment and thetension force on the rope segment must be equal and opposite. So the tension force of the ropeon the rope segment is equal to the friction force on the monkey. But that is all a bit complex.
