X. Input: Force F(t) M has ө mass m Ground 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 mass M is O M*8–2R0+Kr=-F(t) O M*8–2RKO+Kr=-F(t) O M*x+ 2KO+Kr= F(t) O M*7-2RKO+Kx=F(t) O M*X+2RKO+Kr= F(t)
