Answer to Question #60106 in Mechanical Engineering for lil
Question #60106
A vehicle of mass 1010kg accelerates uniformly from rest to a velocity of 62 kmh−1 in 10 s
whilst ascending a 15% gradient. The frictional resistance to motion is 0.65 kN. Making use of
D’Alembert’s principle, determine:
i) the
tractive effort between the wheels and the road surface
ii) the work done in ascending the slope
iii) the average power developed by the engine
