The rate of owner-occupied residences has remained steady since the 1960s.For the first case, a stable and damped system, if there is a change, the system will adjust itself properly to return to steady state. For the other two cases, the system will not be able to return to steady state. For the undamped situation, the constant fluctuation will be hard on the system and can lead to equipment failure.Electrical Engineering questions and answers.
