I have a motor

and i want to attach a spindle, like a circular thing directly onto the shaft.

the circular thing has to have a radius, such that it lifts 0.5kg but does not lift 1kg,
i do not know how to find the radius so it lifts 0.5 but not 1! please help

The specs of the motor are irrelevant, since they can't take into consideration external influences. The output of the gearbox is what matters. All that I can suggest, without breaking the forum rules about helping with homework, is that you should think of your "circular thing" as a lever arm.
