+89 Two wheel gears are connected by a chain. The larger gear has a radius of 5 centimeters and the smaller gear has a radius of 3 centimeters. The smaller gear completes 36 revolutions in 20 seconds.
What is the linear velocity of each of the gears in centimeters per minute?
+36916 The linear velocity of each of the gears is the same because they are connected by the chain (ANGULAR velocity for each is different though)
r = 3 36 revs/20 sec x 60 sec/min = 108 rev/min
3 cm * 108 rev/min x 2 pi /rev = 2035.75 cm/min
