X K g M Input: Force F(t) M has ө mass m Ground R D Ground The figure above shows schematically a translational+rotational system defined by mass M and the disk with mass m and radius R, and a connecting spring with elasticity K. We note that the disk rotates about point D. The inertia J is defined with regard to point D. The system is driven by force F(t) (input) as shown. The output variables are (t) and X(t). The EOM for the motion of inertia J about point D is O J*7+2RKO-2RKy =-F(t) O Oj*+(2R) KO-2 RKr = 0 J = OJ*7 +(2R) KO-2RKY=F() • J*+2K02 – 2 Kr =0 O J* 7+2R²K0-2RKy=0
