If a motor's torque is supposed to be 300g-cm, and I attach a 5cm radius pulley onto it, if I use the pulley to wind some string, and measure the pull with a spring balance, what should it read?
My rather loose grasp of this says it should say 60g, and this seems to make sense - if I double the radius, then the pull should halve, but radius x pull remains the same.
Is this correct?
