Coefficient of Friction Solution

STEP 0: Pre-Calculation Summary

Formula Used

Coefficient of Friction = Limiting Force/Normal Reaction
μ = F_lim/R_n
This formula uses 3 Variables

Variables Used

Coefficient of Friction - The Coefficient of Friction (μ) is the ratio defining the force that resists the motion of one body in relation to another body in contact with it.
Limiting Force - (Measured in Newton) - Limiting Force is the friction generated when two surfaces come in contact with each other.
Normal Reaction - (Measured in Newton) - The normal reaction is the force exerted by a surface on an object in contact with it which prevents the object from passing through the surface.

STEP 1: Convert Input(s) to Base Unit

Limiting Force: 5.125 Newton --> 5.125 Newton No Conversion Required
Normal Reaction: 6 Newton --> 6 Newton No Conversion Required

What is the coefficient of kinetic friction?

The coefficient of kinetic friction is the ratio F/w or mg/Mg , or simply m/M. Based on the data you enter, if the m/M ratio is exactly equal to the selected μ, no motion will occur. To cause motion, you need to slightly increase m, the hanging mass, by 0.1 gram, for example.

What is coefficient of static friction?

The coefficient of static friction is the ratio of the maximum static friction force (F) between the surfaces in contact before movement commences to the normal (N) force.

How to Calculate Coefficient of Friction?

Coefficient of Friction calculator uses Coefficient of Friction = Limiting Force/Normal Reaction to calculate the Coefficient of Friction, Coefficient of Friction is the ratio defining the force that resists the motion of one body in relation to another body in contact with it. This ratio is dependent on material properties and most materials have a value between 0 and 1. Coefficient of Friction is denoted by μ symbol.

How to calculate Coefficient of Friction using this online calculator? To use this online calculator for Coefficient of Friction, enter Limiting Force (F_lim) & Normal Reaction (R_n) and hit the calculate button. Here is how the Coefficient of Friction calculation can be explained with given input values -> 0.854167 = 5.125/6.

FAQ

What is Coefficient of Friction?

Coefficient of Friction is the ratio defining the force that resists the motion of one body in relation to another body in contact with it. This ratio is dependent on material properties and most materials have a value between 0 and 1 and is represented as μ = F_lim/R_n or Coefficient of Friction = Limiting Force/Normal Reaction. Limiting Force is the friction generated when two surfaces come in contact with each other & The normal reaction is the force exerted by a surface on an object in contact with it which prevents the object from passing through the surface.

How to calculate Coefficient of Friction?

Coefficient of Friction is the ratio defining the force that resists the motion of one body in relation to another body in contact with it. This ratio is dependent on material properties and most materials have a value between 0 and 1 is calculated using Coefficient of Friction = Limiting Force/Normal Reaction. To calculate Coefficient of Friction, you need Limiting Force (F_lim) & Normal Reaction (R_n). With our tool, you need to enter the respective value for Limiting Force & Normal Reaction and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Coefficient of Friction?

In this formula, Coefficient of Friction uses Limiting Force & Normal Reaction. We can use 1 other way(s) to calculate the same, which is/are as follows -

Coefficient of Friction = (Centripetal Force*tan(Angle of Friction)+Tangential Force)/(Centripetal Force-Tangential Force*tan(Angle of Friction))
