Coefficient of rolling friction during ground roll Solution

STEP 0: Pre-Calculation Summary

Formula Used

Coefficient of Rolling Friction = Rolling Resistance/(Weight-Lift)
μ_r = R/(W-F_L)
This formula uses 4 Variables

Variables Used

Coefficient of Rolling Friction - Coefficient of Rolling Friction is the ratio of the force of rolling friction to the total weight of the object.
Rolling Resistance - (Measured in Newton) - Rolling Resistance (or Rolling friction) is the force resisting the motion of a rolling body on a surface.
Weight - (Measured in Newton) - Weight Newton is a vector quantity and defined as the product of mass and acceleration acting on that mass.
Lift - (Measured in Newton) - The Lift, lifting force or simply lift is the sum of all the forces on a body that force it to move perpendicular to the direction of flow.
