Compare and contrast the use of D'Alambert's Principles with the principle of Conservation of energy to solve an engineering Problem.
A vehicle of mass 500 kg accelerates up a road that has a slope of 1 in 10, increasing its Speed From 0.5 m/s to 10 m/s while travelling up the road a distance 200m, against a frictional resistance of 51(N.
Determine: (a) a tractive force between the driving wheel and road surface. (b) the work done during the period of the acceleration (c) the average power developed
Your task is:
1. Find above (a), (b) and (c) by using D'Alembert principles 2. Find above (a) (b) and (c) by using principle of 'Conservation of Energy' 3. Compare and contrast both methods by observing you results and comments which method is best suited to solve the example and why? (Minimum 200 words).
