My books say that friction is independent of the area of contact, but only depends upon the coefficient of friction and the weight of body. but well according to my science, there is something wrong with it. because you observe, take same masses but different geometeries for example rectangular area of contact and other having cubic area of contact. then what actually happens the coefficient of friction doesn't remain same i did it in my home. frictional force comes out to be greater. what's this?
if it does not depend upon area of contact why we have wheels?
please some body help me
