It doesn't necessarily change the coefficient of friction. In fact, the C of E probably doesn't vary much, but the amount of actual sliding force is proportional to the torque applied. More torque > more effort to change the length. Just like it taking more effort to slide a one-pound weight along a lubricated track than a 10-pound weight.
