+109 Two gears are connected by a chain. The larger gear has a linear velocity of 27π10 inches per second. The angular velocity of the smaller gear is 15π2 radians per minute.
What is the radius of the smaller gear?
+128460 Since the gears are connected....the smaller gear will move at the same linear velocity as the larger one
So the larger gear travels 60 sec * ( 27pi /10) in /sec = 162pi in / min
So let r be the radius of the smaller gear....then
162 pi = r ( 15pi/2)
162 = r * (15/2)
r = 162 ( 2/15) = 21.6 in
