Kinetic moments

  1. Apr 16, 2017 #1
    Why are kinetic moments not included in the regular summation of the moments? In other words why is the equation ∑M = ∑Mk and not ∑M + ∑Mk = 0 ?

    I guess it would help if someone could explain exactly what a kinetic moment is, and why it is equal to the summation of the moments due to external forces.

    Thanks

    The term "kinetic moment" is not a common usage. I have only 50+ years of doing dynamics, and I have never heard it previously. I suggest that you go back to where you found this term and inquire about it there.
