What is maximum coefficient of friction?

between 0 and 1
The coefficient of friction depends on the objects that are causing friction. The value is usually between 0 and 1 but can be greater than 1. A value of 0 means there is no friction at all between the objects; such is possible with Superfluidity.

What is the minimum value of the coefficient of friction?

The minimum value of the coefficient of friction between the object and the floor of the truck which makes rolling of the object possible is μ≥kga​.

Can you have a coefficient of friction greater than 1?

A coefficient of friction that is more than one just means that friction is stronger than the normal force. An object such as silicon rubber for example, can have a coefficient of friction much greater than one.

How do you find the maximum coefficient of friction?

The maximum or limiting value of friction between two surfaces is FMAX=μR F MAX = μ R where μ is the coefficient of friction and R is the normal reaction between the two surfaces. The coefficient of friction is a measure of the roughness of the surface – the rougher the surfaces the larger the value.

What is the minimum coefficient?

The minimum coefficient of static friction can be obtained from this equation: If the velocity of the car is 72 km/hr (20 m/s) and the radius of curvature R = 190 m, the minimum value of the coefficient of static friction is 0.21.

What is the maximum value of static friction?

limiting friction
The maximum value of the static friction is called limiting friction.

What is the maximum coefficient of static friction?

= μs N
The maximum static friction force is: (fs)max = μs N where μs is the coefficient of static friction. Static friction is subtle because the static friction force is variable and depends on the external forces acting on an object. That is, fs ≤ μs N, while (fs)max = μs N.

What is the maximum value of the static friction?

What happens to coefficient of friction?

Coefficient of Friction is defined as the ratio of the max resisting force parallel to the contact surface to the forces pressing them together. The coefficient of friction can vary depending on whether the body is moving or not. Therefore, by doubling the weight, the coefficient of friction remains unchanged.
