What is Rolling Resistance Coefficient?

Rolling resistance coefficient is the force needed to push (or tow) a wheeled vehicle forward (at constant speed on a level surface, or zero grade, with zero air resistance) per unit force of weight. It is assumed that all wheels are the same and bear identical weight. Thus, they are all just measures of resistance per unit vehicle weight. While they are all "specific resistances", sometimes they are just called "resistance" although they are really a coefficient (ratio).

How to Calculate Rolling Resistance Coefficient?

Rolling Resistance Coefficient calculator uses Rolling Resistance Coefficient = Distance of Opposing Torque from Vertical/Effective Wheel Radius to calculate the Rolling Resistance Coefficient, Rolling Resistance Coefficient formula is defined as a dimensionless value that expresses the resistance to motion of an object rolling on a surface, influenced by factors such as the surface roughness, load, and velocity, providing a crucial parameter in the design and optimization of wheeled vehicles and systems. Rolling Resistance Coefficient is denoted by f_r symbol.

How to calculate Rolling Resistance Coefficient using this online calculator? To use this online calculator for Rolling Resistance Coefficient, enter Distance of Opposing Torque from Vertical (a_v) & Effective Wheel Radius (r) and hit the calculate button. Here is how the Rolling Resistance Coefficient calculation can be explained with given input values -> 0.014 = 0.007/0.5.
