WebTotal Tire Thickness: The puncture force tests are static and test the force required to puncture the casing and anti-puncture layers. To convert from a static lab test value to a more dynamic puncture resistance score, the thickness is used to calculate the total puncture resistance. More Info. Close WebCrr is the vehicle's coefficient of rolling resistance we want to determine Now for some formulas: Fd = -Cd*A*0.5*rho*V^2 (formula for force due to air resistance or drag) Frr = -Crr*M*g (formula for force due to rolling resistance) F = Fd + Frr (total force is the sum of Fd and Frr) F = M*a (Newton's second law) WebIn analogy with sliding friction, rolling resistance is often expressed as a coefficient times the normal force. This coefficient of rolling resistance is generally much smaller than the coefficient of sliding friction. schedule of bar 2022
