Question #1: = A vehicle with the data given below is cruising at constant speed while climbing uphill. Determine the value of the maximum grade that this vehicle can climb. Weight of the vehicle: W = 10000 N Engine moment: Me = 100 Nm Engine speed: ne = 3000 rpm Coefficient of aerodynamic resistance: Cp = 0.38 Total transmission ratio: i = 12 Wheel radius: rw = 0.32 m Vehicle frontal area: A = 1.8 m2 Density of the air: p = 1.2 kg/m3 Tire slip rate: s = 5% Coefficient of rolling resistance: fr = 0.02 Efficiency of the transmission system: ntr = 0.86 = = = Question #2: A vehicle with the data given below is cruising at 90 km/h constant speed on level road. Determine the value of the engine moment required for this vehicle to be able to accelerate with 0.5 m/s2 while the engine is operating at 3600 rpm. Mass of the vehicle: W = 1000 kg Engine speed: ne = 3600 rpm Wheel radius: rw = 0.33 m Vehicle frontal area: A = 2 m2 Density of the air: p = 1.25 kg/m3 Coefficient of rolling resistance: fr = 0.02 Tire slip rate: S = 5% Coefficient of aerodynamic resistance: Cp = 0.34 Efficiency of the transmission system: Ntr = 0.86 =
