does anyone know the friction Coefficient between the carpet and rubber?

[Mark Sheridan]

We have borrowed a spring force meter from the physics lab at our school to determine coefficient of friction. You would have to rig 4 wheels on a light frame and lock them and try dragging the frame with the force meter. you would have to weight everything to complete the friction calculation. Make you make the frame light because the student force meters don't read very much force.

Trying to get bicycle wheels to work may not be worth it. It would be much easier and time efficient to order wheels from Andy Mark with a know coefficient friction that already have the proper mountings to the drivetrain.
