Can the value of the coefficient of friction be greater than 1? |
| Answer» Solution :Value of the COEFFICIENT of friction (`mu`) is usually less than 1. But is some SPECIAL cases its value can be equal to or even greater than 1. The value of `mu` between TWO metal surfaces , cleaned scientifically and KEPT in vacuum may rise up to 10 approximately. Under these conditions `mu ~~1.6` between two copper plates. | |
