Angular Speed of a Sprocket

  1. Dec 22, 2008 #1
    The drawing (attached) shows the blade of a chain saw. The rotating sprocket tip at the end of the guide bar has a radius of 3.8 10-2 m. The linear speed of a chain link at point A is 6.5 m/s. Find the angular speed of the sprocket tip in rev/s.

    Vt= w/r

    6.5= w/ .038

    w=.247 rev/ sec

    .247 was incorrect and I am unsure of what I am missing from my equation

    hmm your formula is wrong

    [tex] V=\omega \times R [/tex]
