IMPERIAL Grade Resistance The grade resistance of a vehicle is .01 times the gross weight times the percentage grade. GR= .01 x GVW x % grade Where:GR = Grade resistance GVW = Gross vehicle weight Example:What is the grade resistance of a vehicle having a gross weight of 10,000 lbs. on a 5% grade? GR = .01 x 10,000 x 5 = 500 lbs

METRIC Grade Resistance The grade resistance of a vehicle is .0981 times the gross weight times the percentage grade. GR= .0981 x GVW x % grade Where:GR = Grade resistance in newtons GVW = Gross vehicle weight in kilograms Example:What is the grade resistance of a vehicle having a gross weight of 4,500 kg. on a 5% grade? GR = .0981 x 4,500 x 5 = 2207.25 N
