Whenever their is a movement, friction comes into action. The same is the case with earth moving equipments. We term this as rolling resistance and this has to be overcomed by vehicle engine so that it can move on that surface. This is the formula to calculate rolling resistance R=RfW + RpPW where R = rolling resistance, lb (N) p = tire penetration,…
