A fixed pulley like structures in the human body: Movement of the knee joint: The fixed pulley principle is used to extend the knee. WebThe formula for the m.o.i. of a pulley is 1/2mr^2, where m is the mass and r is the radius. So the m.o.i. of your pulley would be I=1/2*5kg*.25m^2=.156kg*m^2. The product of the m.o.i. and the angular velocity is going to equal the torque (rotational force) on the pulley. The tension in the rope, in turn, is equal to the torque on the pulley ...
