Engineering Design Process Review

1. A tire company is creating a new tire for a motorcycle to drive off-road in sandy and rocky conditions as well as on roads. Engineers developed three different tread patterns. Based on the engineering design process, the next step the company should take is to:

• Send out a questionnaire about tires to the public

• Select which tread design will be best

• Research the properties of rubber

• See which tire is the most expensive

1. Rob and his team have been chosen to build a wind turbine at a local ski resort that needs to generate electrical energy and withstand the harsh environment of the mountains. Rob and his team have done their research on the problem. What would be the next step for the team?

• Create a prototype of the wind turbine

• Develop possible solutions(s) for the turbine and how it will fit the criteria needed

• Test the wind turbine on the mountains during the harsh winter months

• Redesign a new solution for this turbine

1. Students have a box of ice pops to take to their soccer game to sell on a hot day. The students know they need a device to keep the ice pops from melting for 3 hours. They have a $15 budget. Which step of the engineering design process does this demonstrate

• Identify the problem

• Test and evaluate

• Redesign

• Develop possible solutions

Brian is trying to create a motorized scooter for his engineering design project. Which of the following should he do during his research step?

• Look up current scooter design online

• Ask professionals who work at the local scooter shop

• Read the instruction manuals for other scooters

• All of the above

Which step does #3 represent

• Evaluate the solution

• Identify the problem

• Construct and test Prototype

• Develope a Solution

In which step do you answer the question "Is the problem worth solving?"

• Present a Solution

• Design Brief

• Identify a Problem

• Generate a Solution

Which of the following is most likely part of the testing and evaluation stage of designing a smart phone?

• Writing an advertisement for the smart phone

• Defining the specifications for the smart phone

• Finding the plasticity of a new alloy to be used for the smart phone case

• Trying the smart phone with a range of voltages to determine when it will fail

A set of steps engineers follow to complete the design of an object or idea is called the

• The Scientific Method

• The Engineering Design Process

Before you create your prototype their are important steps to take in the Engineering Design Process. What are they?

• Redesigning

• Test and evaluate your solution

• Communicate your results

• Identify your need or problem

Why is feedback important when designing a product?

• It helps the engineer learn the glitches of the product

• It lets the engineer know what works and what the consumer likes about the product

• It helps the engineer to improve the product.

• It lets the engineer know how the community would react to the product, if they like it or not
