Re: Calculating Linear Force from Motor Torque?

Are there any calculations that need be taken into account regarding the pinion gear teeth number or the length of the rack or whatnot?
The pinion teeth number would be used to find it's radius, the length of the rack wouldn't matter for the current calculations (but could be used for calcs like how much energy is required to traverse the entire rack, etc...).
