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?

Yes
yes, but motors when stalled may not deliver peak torque.
The classic dynamometer uses a brake band on a pulley connected to a spring balance, to measure torque while running.
Ask J. Clarkson. He's always on about how many "talks" a car has - and he's a real wind-up. I know it's all for effect - but I do wish we'd get a proper look at the machanical bits. More than 10ns anyway.
