One elevator arrangement includes the passenger car, a counterweight, and two large pulleys, as shown in $($ Figure $1).$ Each pulley has a radius of $1\mathrm{.}5$ m and a moment of inertia of $400kg*m^2.$ The top pulley is driven by a motor. The elevator car plus passengers has a mass of $3000$ kg $,$ and the counterweight has a mass of $2800$ kg $.$
