Technology Basics
What is the definition of Technology?
Anything created by humans to solve a problem or meet a need or want
A design requirement that tells what a successful solution should accomplish is called what?
Constraint
How many steps are there in the Engineering Design Process? (Hint: We reduced it for the purpose of this class)
5
What two digits are used in binary?
0 and 1
A wind turbine belongs primarily to which context?
Energy & Power.
What is the difference between an invention and innovation?
An invention is something new; an innovation improves or changes something that already exists
A design requirement that tells what a successful solution should accomplish is called what?
Criteria

A factory turns raw metal into car parts. Which context is this?
Material Processing.
People wanted cars to be safer, so engineers developed airbags and improved seat belts. Is this society influencing technology or technology influencing society?
Society influencing technology.
Students may use only 10 sheets of paper and 24 inches of tape to build their tower. Is this a criterion or constraint?

A warehouse uses programmed robots to automatically sort packages. Which context is this?
Computation, Automation & Robotics.
Give an example of how technology can influence society.
Answers vary; e.g., smartphones changed how people communicate.
You are designing a bridge. It must hold at least 500 grams, must be less than 30 cm long, and you may use only 20 craft sticks. Identify the criterion and the two constraints.
Two bridges both hold the required weight, but Bridge A costs less and the project has a strict budget. Which should engineers choose and why?
Bridge A because it meets the criteria while better satisfying the budget constraint.
