Answer:
In engineering design, failure is expected. It helps you find the best solutions before implementing them in the “real world”. Having a prototype fail is a GOOD thing, because that means you have learned something new about the problem and potential solutions.

Answer:
The annual operating cost of the refrigerator is $102.78.
Explanation:
Power consumed by the refrigerator = 247 W = 247/1000 = 0.247 kW
Daily operation of the refrigerator = 19 hours
Annual operation of the refrigerator = 365 × 19 = 6,935 hours
Annual energy consumed = 0.247 kW × 6,935 hours = 1712.945 kWh
1 kWh of electricity cost $0.06
1712.945 kWh will cost 1712.945 × $0.06 = $102.78
Annual operating cost = $102.78
