Question 980514
Two pulleys, one 6 in. and the other 2 ft. in diameter, are connected by a belt.  The larger pulley revolves at the rate of 60 rpm.  Find the linear velocity in ft./min. and calculate the angular velocity of the smaller pulley in rad/min.
---------------
Circumference = pi*d = 2pi ft
LV = 2pi ft * 60 rev/min = 120pi ft/min
---------
The smaller pulley is 1/4 the diameter --> 4x the rpm = 240 rev/min
Each revolution = 2pi radians
w = 240*2pi rad/min
