How to Find Coefficient of Static Friction?
Higher the value of static friction coefficient, higher is the frictional force exerted between two surfaces. The value of this coefficient of static friction cannot be determined theoretically. It can only be determined empirically through experiments. For most materials, the static friction coefficient ranges between 0.3 and 0.6. No material object has a value of zero for the coefficient of static friction. Materials like teflon do have static friction coefficient close to 0.04. Some objects like silicone rubber can have a static friction coefficient to be greater than 1. The coefficient varies according to the nature of the surfaces that are in contact with each other. The coefficient of static friction between two surfaces depends on their physical and geometric properties. Hope this article has clarified the concept of static friction coefficient to you. It is an important parameter that needs to be taken into consideration in machine designing or in designing of any system where
