Precession Nutation and Spin

  1. Jan 12, 2012 #1
    Hi guys !

    Im trying to get my head round precession, nutation and spin.

    Suppose I have a cylinder of height L, base radius R. Initially it is just spinning about its central axis (i.e. line joining cone tip to the centre of base). In this scenario,

    centripetal acceleration experienced by say an accelerometer placed on the radius of the base would be = Rω2.

    However when it starts spinning and nutating with angular velocities say ωP and ωN,

    am I right in thinking ω = √ω2P2N ?

    And also, what would my sensor 'experience' now that it is nutating and precessing ? Im guessing it would be a Rω2 sin term but this time 'R' would be a time dependent function and not constant. What do you think ?
