Enter the rolling resistance coefficient and the normal force into the calculator to determine the rolling resistance. This calculator helps in estimating the resistance force that opposes the motion when a body rolls on a surface.
Rolling Resistance Formula
The following formula is used to calculate the rolling resistance:
RR = Crr * N
Variables:
- RR is the rolling resistance (N)
- Crr is the rolling resistance coefficient (dimensionless)
- N is the normal force (N)
To calculate the rolling resistance, multiply the rolling resistance coefficient by the normal force acting on the body.
What is Rolling Resistance?
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.
How to Calculate Rolling Resistance?
The following steps outline how to calculate the Rolling Resistance.
- First, determine the rolling resistance coefficient (Crr).
- Next, determine the normal force (N) acting on the body.
- Use the formula RR = Crr * N to calculate the rolling resistance (RR).
- Finally, input the values into the calculator to verify the result.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Rolling resistance coefficient (Crr) = 0.02
Normal force (N) = 1000 N
