Dear engineers, I want to find the normalized stiffness for the machine with unbalanced force Ps_s(t)=P0 sin w0t and also the steady-state transmitted force fs_s(t)= f0 sin(w0-phi). and the given parameters are w0*t0=50*pi. Then I want to find the analytical expression of the phase angle and angular velocity and unbalanced force. Also in the attachment, I uploaded the problem. I really appreciate if somebody can refer me to the relevant example or topic can help to solve this problem or even part of that. Regards
