Of course, but if we assume ideal conditions which are impossible in reality, will the resulting force on the teeth be constant if we apply a constant torque to the motor/a constant current, and it will accelerate into infinity?

Oh i understand. And if we assume no friction or terminal speed there will be always be the same normal/reaction force?

Thank you! This Makes sense. I have one last question. When i asked on reddit a couple of days ago i got a reply: „The forces on the gear are going to accelerate it, and this will mean that the normal force on the rack and the reaction on the gear goes down.“ What did he/she mean by that?

Thank you so much, but if there were resistance where and how would it act?

I wrote that haha. But i simplified it and got here to understand it haha. The geer would be suspended by a wheel above the rail, supporting it, but i already accounted for that by drawing in force B. The gear would have an applied torque coming from a motor

I am confused cause in my diagram for the sake of simplicity i ignore gravity and friction. But the net torque on the gear is zero? How can that be? I am sorry if thats a stupid question but i am just a bit confused and honestly stuck since days on that. F react. Is the force that causes the...
