Question 1 [20] The centre of gravity of a vehicle shown in Figure 1 is 800 mm from the surface of the road and 1.5 m from the rear wheels. The wheelbase is equal to 2 m. The coefficient of friction between the surface of the road and the front driving wheel is equal to 0.25. When accelerated from rest, this vehicle can reach an acceleration of (a m/s²) in 5 seconds. Whereas the vehicle engine speed is 250 rpm. If the vehicle has wheel radius of 250 mm, calculate the speed ratio of the first pair of gears selected in gear box. The front wheel shafts are directly connected to the output shaft of the gear train of the vehicle. Whereas the engine) is connected to the input shaft of the gear box. 800 mm 1.5 m Figure 1: Vehicle Question 1 [20] The centre of gravity of a vehicle shown in Figure 1 is 800 mm from the surface of the road and 1.5 m from the rear wheels.
