Equation of equilibrium of a SDOF

  1. Dec 8, 2015 #1
    Hi guys! I would really need some help with a problem I have over here:
    how do I you get the equations of equilibrium for the scheme in picture of the single degree of freedom system? I am having some trouble understanding why I have m1*Hc*(H*theta_0) mostly, but also about why I have moment of inertia I_i*rotation or mass*displacement; shouldn't it be m*a and I*angular acceleration? or does the multiplication with angular frequency make this? I appreciate all answers related to this topic.

    Yours truly,
