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...

3. Consider the investment project given in the below table: An electric motor is rated at 10 horsepower (HP) and costs $1,200. Its full-load efficiency is specified to be 85%. A newly designed high-efficiency motor of the same size has an efficiency of 90%, but it costs $1,600. It is estimated that the motors will operate at a rated 10 HP output for 2,000 hours/year, and the cost of energy will be $0.09/kilowatt- hour. Each motor is expected to have...

Galt Motors currently produces 500,000 electric motors a year and expects output levels to remain steady in the future.

A question from Corporate Finance, by Berk&DemarzoGalt Motors currently produces 500,000 electric motors a year and expects output levels to remain steady in the future.
