The formula to calculate the Rolling Resistance (RR) is:
\[ RR = Crr \times N \]
Where:
Rolling resistance is the force that opposes the motion when an object rolls on a surface. It is caused by the deformation of the wheel or the surface, or both, during rolling. The rolling resistance coefficient is a dimensionless value that represents the ratio of the rolling resistance force to the normal force. This coefficient varies depending on the materials, surface texture, and other factors. Understanding rolling resistance is crucial for designing efficient vehicles and for calculating the energy required to maintain motion.
Let's say the rolling resistance coefficient (Crr) is 0.02, and the normal force (N) is 500 Newtons. Using the formula:
\[ RR = 0.02 \times 500 = 10 \]
So, the rolling resistance (RR) is 10 Newtons.
