Chapter 6: Friction_1
Friction
1. For most of the
surfaces used in daily life, the friction coefficient is less than 1. Is it
always necessary that the friction coefficient is less than 1?
Solution: It is not necessary that the
friction coefficient is always less than 1. When the friction is stronger than
the normal reaction force, the coefficient of friction is greater than 1. For
example, silicon rubber (or rubber on rubber) has the coefficient of friction
greater than 1.
