DI 10:08 the speed variation for Belt 1(Alternator - Crankshaft): Avbelt1 : m/s and and Avbelt2 m/s for belt 2 (Crankshaft - Pump - Compressor). The angular acceleration of each pulley are respectively, • Aalt = rad/s? • Acr rad/s? aps rad/s? • Aac rad/s2 The linear distance covered by a point on each belt during acceleration are m for belt 1 and m for belt 2. The total number of revolutions at the A/C compressor during acceleration is rev The total acceleration time, tacc II ||
