Can someone explain why the maximum coefficient of friction is 1??
Why μ <= 1 ?
Thank You.
Why μ <= 1 ?
Thank You.

ferranvalles said:But if you are talking about glues and something like this, you are not talking about friction, it's a different force.
For definition, when the coefficient of friction is m:
0<=m<=1
And I wonder, why m<=1?

Now I understand the coefficient friction can be higher than 1.
Another explication is that in a ramp, the coefficient of friction is equal to the tangent of ramp's angle.
The angle can be higher than 45º, so the tangent would be also higher than 1, as a consequence we can get a coefficient as high as we want (considering that a body is holded in the ramp).
The maximum coefficient of friction is the maximum amount of friction that can be generated between two surfaces in contact with each other.
The maximum coefficient of friction is calculated by dividing the maximum force of friction by the normal force. This can be represented by the equation μmax = Fmax / Fn.
The maximum coefficient of friction can be affected by several factors, including the types of surfaces in contact, the roughness of the surfaces, and the presence of any lubricants.
The maximum coefficient of friction is an important concept in engineering, as it helps to determine the maximum amount of force that can be applied to a structure before it begins to slip or slide. It is also used in designing brakes for vehicles and determining the safety of different types of flooring.
The maximum coefficient of friction is the upper limit of the coefficient of friction, while the coefficient of static friction is the actual value of friction between two surfaces at rest. The maximum coefficient of friction is always higher than the coefficient of static friction, as it takes into account the force required to overcome static friction and initiate motion.
