Rotational Motion Ranking

Text

Two identical black masses, m,  are hung via massless strings over two pulleys of identical mass M and radius R, but different mass distributions as shown in the animation (position is in meters and time is in seconds). The bearings in the pulleys are frictionless and the strings do not slip as they unwind from their pulleys. Start

• In which direction is the angular acceleration of the pulleys?

• Which pulley has the greater moment of inertia? 

• In which simulation is the torque acting on the pulley the greater?
