Design a control for four electric motors. Motors 1, 2, and 3 are to be controlled separately. When any one of the three starts, motor 4 is to start. Motor 4 can also be started independently of the others. If any motor reaches an overload condition, it will shut down all of the motors. In addition, there is to be a master start-stop switch (momentary) to make it possible to manually shut down all operating motors at once. The master...

The following is a list of six control plans from this chapter or from Chapter 9. These are followed by a list of six statements describing either a control goal or a system deficiency. Match the five control goals or system deficiencies with a control plan that would best prevent the system failure from occurring. Because there are six control plans, you should have one letter left over. Control Plans A. One-for-one checking of the goods, picking ticket, and sales...
