A four-inch-diameter pulley on an electric motor that runs at 1900 revolutions per minute is connected by a belt to an eight-inch-diameter pulley on a saw arbor.
(a) Find the angular speed (in radians per minute) of both pulleys.
(b) Find
Angular speed of the 4" pulley is 1900*2*ПЂ = 11938.052083641214306158044856462
say = 11938 radians / mi. and the 8 " pulley angular speed = 5969.0260 say 5969 rad./ min.
The saw runs 950 revolutions per minute .
