Torque is calculated linearly. Double the amount of motors, double the amount of torque.

*This is assuming all motors have the same or similar output speeds. Of course adding a motor that's twice as fast as the original motor is going to speed things up a bit, but that's a situation you should rarely come across in FRC. CIMs and Mini CIMs, for example, are about the same speed.

Oh ok, so if you add M amount of cim motors then your torque increases by xM? Like having two CIMs means double the amount of torque and three CIMs triples the amount of torque?
