1.3.1 What is Engineering?

1.A team of engineers is asked to evaluate several different design solutions. Which statement about criteria and constraints is true?

• Constraints are more important than criteria.

• They are more useful if they include numerical values.

• Criteria are more important than constraints.

• They are more useful if they include qualitative values.

2.A team of engineers is asked to evaluate several different design solutions. Which statement about criteria and constraints is true?

• They produce more useful design solutions when they include qualitative values.

• They must be the same to result in the best design solutions.

• They result in better design solutions when they are specific.

• They must be as simple as possible to produce the best design solutions.

3.A team of engineers is asked to evaluate several different design solutions. Which action is most likely to help them with their evaluations?

• Changing the constraints to match the design solution they like the most

• Asking detailed questions about the criteria and constraints

• Deciding which design solution is least costly without considering the criteria

• Asking who developed the project's criteria and constraints

• Farmers in hilly areas grow crops on terraces built on the hillsides.

• Farmers make more money by using modern farming machines.

• Farmers work harder than bankers to make a living.

5.Which statement is the best example of how society affects the use of technology?

• People who make a lot of money tend to buy new cars with the most modern features.

• Larger vehicles that use gasoline release more carbon dioxide than smaller gasoline-powered cars.

• Researchers are developing solar-powered cars that can travel long distances.

• People who sell cars make more money when the supply of new cars is low.

6.Which statement is the best example of how society affects the use of technology?

• Some people who are concerned about climate change get their power from solar or wind energy.

• Irrigation systems are used to deliver water to crops that grow in fields.

• Solar panels can generate power in parts of the world where there is plenty of sun throughout the year.

• Regions that are sunny most of the year have more farms than cold regions.
