A motor vehicle of total mass 5.7 Mg starts the ascent of a 1 in 50 gradient at a speed of 32 km/h and maintains a constant tractive effort of 3.5 kN throughout the total length of 600 m. The road resistance amounts to 350 N/t. After the ascent, it has to travel along a straight level stretch of 150 m in length before taking a bend of 45 m radius. The roadway at the curve is unbanked and the coefficient of friction against side slip is 0.4. Determine the uniform tractive effort that is permissible on the 150 m length if the vehicle is not to reach a speed at the curve in excess of that at which skidding would occur. (2.302 KN).
