Engineering Design Process
What is always the first step of the engineering Design process?
Identify the problem or need
On a solar panel, sunlight entering the system is an example of what? input, output or component?
Input
What word describes the requirements a design must meet/limits (like cost or size)?
Constraints
A new microscope helps scientists study cells better. Is this an example of science influencing technology or technology influencing science?
Technology influencing science.
What is the definition of trade-off?
Giving up benefit in one area in order to gain benefit in another area.
Why do engineers build small working models before building the real thing?
To safely and more cheaply test how changes affect the whole system.
Heat escaping from a device is an input, output or component?
output
What word describes what the design is trying to achieve/goals?
Criteria
Discovering a new molecule leads scientists to built a new type of sensor. S-T or T-S?
Science influencing technology
Give an example of a trade-off?
Let me hear them!
What is the main reason engineers test prototypes?
To see if the design meets the criteria and constraints.
A model of a water cycle includes evaporation, condensation and precipitation. What kind of system does this represent?
Natural System
A skateboard must stay under $10 to build. is that a criterion or constraint?
Constraint
DNA fingerprinting improves because scientists learn more about DNA. S-T, T-S?
Science influencing technology
What is the difference between a designed and a natural system?
Designed: Made by humans on purpose, built to do a specific job or solve a problem. Planned parts that work together
Natural: Exists in nature and not made by humans. Parts still interact and work together. Follows natural processes
After testing a prototype, engineers usually revise it. What is this step called?
Redesign/improve the solution
Wheels are an example of a ____ on a skateboard?
Component
A bouncy ball must bounce the highest of all designs/ Is this a criteria or constraint?
Criteria
Telescopes become stronger, letting scientists discover new stars. S-T or T-S?
Technology influencing science?
If you don't understand a question the first time you read it, what should you do???
Reread it. Ask the teacher if you still are confused after multiple re-readings.
What is the last step of the engineering design process?
Implementing the improved design on a large scale.
Changing one part of a system affects other parts. This idea is called what?
System Interaction
If a design meets the criteria but breaks a constraint (doesn't meet it), what must the engineer do next?
Redesign it so it fits all the constraints.
Medical researchers develop better treatments after learning more about viruses. T-S or S-T?
Science influencing technology. Hello!
What is an important word that starts in d and ends in ails that you should be sure to study and include in any short answer questions?
dogtails
just kidding.
