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 Newton - (Measured in Newton) - Weight Newton is a vector quantity and defined as the product of mass and acceleration acting on that mass.
Lift Force - (Measured in Newton) - The Lift Force, 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.
STEP 1: Convert Input(s) to Base Unit
Rolling Resistance: 5 Newton --> 5 Newton No Conversion Required
Weight Newton: 60.34 Newton --> 60.34 Newton No Conversion Required
Lift Force: 10.5 Newton --> 10.5 Newton No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
