Is there a simple way to estimate the rolling resistance of a vehicle by rolling it down a known incline with a variety of weights?
In short, if the velocity of a vehicle rolling down a ramp is a function of the air resistance and the rolling resistence and if rolling resitence is proportional to vehicle weight ( is this correct? ) can one come up with estimates for
CdA and Rolling resistence by rolling the vehicle down a known incline with various changes of weight? If not, is there a methology whereby one can measure the rolling resistance of a vehicle or measure changes to that figure of merit in relative terms?
