Endurance tester for rubber material

[SR71-110]

Hi All,
I am working on a project similar to this (

My question is how we can size a motor for such a system. If my wheel is pushing on the drum with a vertical force, what would be the best way to record the horizontal force (Slippage) on the wheel.
Also, I have different sizes wheels Is it better to attach the motor to the drum or the wheels?

Any suggestions would be appreciated.

Thank you.

Can you tie all of your recent posts into a more complete package using just one post? You might get some better suggestions if you were more forthcoming (and provided better sketches). If the project is proprietary, you probably need to enlist a paid professional.
