Thermodynamics studies the interconversion of different types of energy. Which of the following is true regarding thermodynamics?

The 1st law of thermodynamics states that the energy cannot be created or destroyed

All usable energy eventually degrades to a non-usable form of thermal energy

The first law of thermodynamics only applies to isolated systems

Which of the following is true regard the development of engineering disciplines?

Electrical Engineering arose during the 2nd Industrial Revolution in response to the advances in electricity

Engineering disciplines & sub-disciplines are more likely to form when technological advancement is changing rapidly

Chemical Engineering arose during the 1st Industrial Revolution in response to advances in chemistry and food production

During ideation and concept evaluation using a divergent-convergent process

The convergent phase requires disciplined application of selection criteria to identify the best ideas

In the deferral of judgement phase, silly ideas are encouraged

In the divergent phase, participants freely share their judgements regarding the quality of other participants' ideas

There are many methods for evaluating concepts. Which statements are true?

All evalution methods require selction criteria to judge the concepts against

Reduction of large number of concepts to the few best often requires the use of more than one evaluating technique

Dot voting is a quick way to reduce the number of concepts under consideration

Which of the following regarding the licensure of engineers is/are true?

To become a licensed engineer, you must pass the Fundamentals of Engineering Exam and work for at least 4 years under a licensed engineer's supervision after graduating with an engineering degree

Only professional licensed engineers may work on drawings for aircraft

The Army Corps of Engineers oversees professional engineering licensure throughout the US

Which of the statements regarding the specifications and design targets are true?

Specifications restate the stakeholder requirements in a measurable way

Specifications may be direct performance measures

Specifications are never relative performance measures (ex. A preferred to B)

Which of the following regarding the differences in how various disciplines test preliminary designs are true?

Mechanical engineers often produce small products that can be prototyped that can be prototyped at full-scale and test in most types of testing, including consumer testing

Electrical and Chemical engineers design processes and test them at several scales for scale-up purposes

Civil engineers typically build full-scale prototypes to test the structural design

Final design reports should include:

The justification for the project

All of the detailed design drawings necessary to execute the project

A discussion of the critical design decisions and trade-offs made during the project

The product lifecycle:

Is the path a product takes from raw material extraction to final disposal

Is useful for identifying potential stakeholders

Is used to determine how long a product remains in the market before requiring a redesign

As the design moves from conceptual design to preliminary design, and then final design:

The cost estimate becomes more precise

The cost to develop the cost estimate decreases

The schedule becomes less detailed

Team conflict is likely when

The members have incompatible work styles

There is shared leadership and decision making

The teams are in Tuckman's performing state of group development

An engineer is hired to design a pedestrian bridge for a community. The engineer realizes during the design process that a less expensive material could be used to save money. However, the material does not meet safety standards and may degrade quickly under environmental stress, potentially endangering pedestrians. Despite this, the engineer proceeds with the design, choosing the cheaper material to secure future contracts with the client.

An engineer is tasked with designing a water purification system for a rural community. Although the engineer has expertise in structural engineering, they accept the project without consulting or collaborating with specialists in water treatment. As a result, the system is poorly designed and fails to function effectively.
