Could someone comment on how much torque the belts components can take? I'm thinking of two applications in particular.

First, if I want to do a WCD with 4" (or even 6") wheels, what is the right toothcount pulley to use, given that I want a reasonable factor of safety? Let's just say that I want to be able to have the robot traction limited (instead of ratcheting limited) when it's reared up on two wheels.

Second, if I use a 60T pulley and a 15mm wide belt, could I use it to raise an arm? What about the shock loads that the arm would see when it changed directions? Would the belt ratchet under those conditions? What if I wanted to raise the robot up on the arm, a'la 1538?

Generally, could you publish some kind of torque ratings for these components?
