A newly constructed bridge was inspected to evaluate the load capacity of the bridge. During the inspection, fatigue cracks and stress fractures were discovered on the deck and supports. After reviewing the original plans, it was discovered the bridge was not built to original specifications (requirements). What did the engineers most likely ignore when designing the bridge?

• Planning and developing

• Criteria and constraints

• Testing the bridge

• Safety procedures

A new office building has been planned and will be built in sunny, Phoenix, AZ. The roof will have a three foot overhang and the exterior walls will be constructed using twelve inch adobe brick. The design features of this building have been established based on:

• financial conditions.

• environmental conditions

• enterprise conditions

• usage conditions

Which design constraints are likely to compete with each other when designing a fuel cell for a rocket?

• Color and material choice

• Programming and ease of use

• Weight and power output

• Warranty and radioactivity

The process used to make a design or system as effective or efficient as possible.

• Optimization

• Complex systems

• Nuclear Energy

• Divergent thinking

An engineer designing a laptop is told the device should be convenient to carry. This is likely to affect the design process, creating constraints on:

• size and weight

• handle features

• processor speed

• applications and functions

The advancement of scientific knowledge is promoted by using:

• The advancement of scientific knowledge is promoted by using:

• mythology as a starting point for explaining the natural world.

• mythology as a starting point for explaining the natural world.

• aesthetics and its effect on the marketability of the product.

The purpose of a case study when conducting problem-solving research is to:

• select an appropriate solution to a problem.

• document where and how others have made mistakes in solving a problem.

• make sure the designer has not stolen other's solutions or ideas.

• assess the current understanding of a problem.

Many airplanes are constructed largely out of aluminum even though steel is a stronger material. This is an example of:

• choosing a more economical solution.

• designing for recycling.

• optimizing design trade-offs.

• developing a simple manufacturing system.

Considering the given criteria and constraints, competing factors that will jeopardize the product's efficiency will require a:

• budget.

• specification.

• spin-off

• trade-off

High school students are developing a Technology Education website to educate the local community about the school’s Engineering Design program. Which question is most likely to be asked in the problem analysis phase of the engineering design process?

• Who will be viewing the web site?

• How will the success of the web site be measured?

• What does the community need to know about the program?

• Are both sides of an issue included in the website?
