The monkey climbs the rope trying to get the banana seen http://home.earthlink.net/~urban-xrisis/clip002.jpg [Broken](adsbygoogle = window.adsbygoogle || []).push({});

I need to find the net torque and the total angular momentum about the pully axis.

I am absolutly stumped but I'll give it a shot. So the monkey is moving upwards that means it has to sustain and move its own body. That means it has to apply a force of Mg to hold onto the rope and Mg to move up the rope. The total force is 2mg. Total torque would be the force of the monkey (2Mgr) plus the banana (Mg) which equals 3Mgr right?

For the angular momentum, that is the integral of torque. Does that mean angular momentum is [tex]\frac{3Mgr^2}{2}[/tex]

any help?
