I have a motor

http://www.megabuy.com.au/gearbox-wi...utm_medium=cpc

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

]2. Homework Equations

F=ma, Torque=F*r

3. The Attempt at a Solution

i am having trouble as i don't think these formula's are the only ones i need. also the unit for toque is in a weird form and i don't know how to aplly it.

if i try to sub what i know into Torque=F*r, it doesn't work out.
