Torque to force conversion (from a motor)

How to convert the torque from a motor to a force

So this is a silly problem that I ran into at work which made me realize that I have all but forgotten Newton's laws of motion after years of working with just hardware and software.

I am in the middle of programming a robot for an industrial application and I realized that I have no clue how to convert the torque from a servo motor into a force.

Basically imagine the following: you have a vehicle with 4 wheels coming up an assembly line. In the middle of this vehicle there is a metal weight what will be clamped with X N of force. A torque will then be applied to the piece at 20,000 Nm. I'm utterly confused, will any of the 4 wheels on the vehicle need to absorb any of the torque? When I think about it just intuitively I feel like the metal weight will have a tendency to rotate and that it will thus push down on the vehicle, but that will be seen as a force applied from one side of the metal piece that is in contact with the vehicle.

Thust the total force on the vehicle should be Ftot = Fweight + Fclamp +Ftorque->force

Or am I completely missing something?

What is the direction and fulcrum of that torque?
How does the servo that you have mentioned fit in the problem?
Any schematic?

Yes. You are missing a diagram showing what you want to do.
