It is going to depend greatly on the type of fabric used for the cloth. You can determine it yourself by fastening a taut sample of the cloth to a smooth piece of wood, placing the rubber sample on the cloth covered wood, then slowly lifting the wood at one end to form an inclined plane. When the rubber starts to slide, measure the angle of the incline. The static friction coefficient is then determined in accord with the Laws of Physics. Is this homework?
Thanks for the response
It is for a university project. the rubber is a RC car tyre and the cloth is from a belt sander. I dont think the layout you suggested would work for this case, do you have any other ideas?
