Criteria & Constraints

The general requirements and limitations that are incorporated into the design of a structure are known as:

• creativity and innovation.

• form and function.

• criteria and constraints.

• marketability and safety.

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

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

• budget.

• specification.

• spin-off.

• trade-off.

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.

A speedboat is not permitted to go faster than 100 knots in a lake. Therefore, the company decides to redesign the throttle so it cannot exceed 95 knots. This is an example of:

• constraint.

• criteria.

• trade-off.

• design challenge.

A design team is making a new container for milk, and the customer needs the container to be tall. The size specification is considered a:

• criteria.

• constraint.

• limitation.

• function.

The requirements for a product to function efficiently are called:

• trade-offs.

• impacts.

• collaborations.

• criteria.

Identifying both desired elements and limitations of a product or system is called determining:

• requirements.

• resources.

• recommendations.

• risks.

A design challenge is given that says, create a birdhouse, but do not let it cost more than $20.00 in materials. The cost of the birdhouse would be considered a/an:

• criterion.

• constraint.

• requirement.

• example.

The criteria and constraints of a product or system, and the determining factors on how they affect the final design and development, are called:

• requirements.

• resources.

• recommendations.

• risks.
