Technology and Design Quiz

Which of these is an example of technology?

• developing a hypothesis

• formulating a new theory

• a sketch of an engine

• an artificial hip-replacement

An engineer designed four braces to offer comfort and support for people who have had knee surgery. The table below shows the results from a survey of 100 people who tried the engineer’s four prototype braces. What can the prosthetic designer assume from the information in the table?

• Brace A is preferred by a majority of the people surveyed.

• Brace B would most likely keep people from becoming injured again.

• Brace C would be the best choice for comfort and support.

• Brace D is the brace that can most likely be improved by further design.

Sometimes a new product is test-marketed. A limited amount of the product is released to a group of users. Then the group is observed to see how the product performs. Which step might occur in the design process after a product is test-marketed and before it is mass-produced?

• The design is detailed in drawings.

• The design is measured and evaluated.

• The product design is copyrighted and patented.

• The product is redesigned based on evidence that is observed and gathered.

Which of the following activities is often a first step in the creative design process?

• developing charts

• testing a prototype

• brainstorming ideas

• using a computer program

A bioengineer is developing a prototype for an improved mechanical heart valve from an older model. Which is the best possible purpose of the prototype?

• to see how the heart valve actually works

• to determine how the valve can be made and produced

• to see how well the improved heart valve meets the design criteria

• to see if they can build the improved valve with less expensive materials

Scientists or engineers often build a prototype of a design that they can test. Observing how the prototype performs shows the engineers how their design works. Which is another tool scientists use that is similar to a prototype?

• a balance

• a bar or circle graph

• a model of the design

• an experiment using the design
