Engineering Process
The first step of the engineering design process.
Identify the problem.
This macronutrient helps your body build tissues like muscle and bone
Protein
An early sample of a product that provides information about how the device or system works.
Prototype
Any representation of a system or its components.
Model
Someone who uses science and tools to build a product that solves a practical problem
Engineer
True or false: failure during the engineering process is normal
True
The main artery in the human body
Aorta
The requirements of a design
Criteria
The limitations of a design (usually cost, time, and materials)
Constraints
Someone who pursues understanding of the natural world by using evidence to answer questions.
Scientist
Some challenges engineers face are:
Environmental impact of their designs, social and economic concerns, availability and cost of materials
Three macronutrients that make up most of food
Carbohydrates, fats, and protein
To make better or as good as you can
Optimize
A changing factor that is studied
Variable
Any product or process made by engineers and often used by scientists
Technology
A wood ruler can hold 200g before breaking. The ruler itself has a mass of 20g. What is the ruler's strength-to-mass ratio?
10 (or 10:1)
The pancreas of someone with Type 1 diabetes does not produce this hormone
Insulin
A desirable outcome given up to gain another desirable outcome
Trade-off
To conclude by reasoning from known facts
Infer
A structure in the heart that controls blood flow
Aortic valve
Steps of the engineering design process
Identify the problem, brainstorm solutions, design/plan, build/create, test and evaluate, re-design/improve (and re-test, re-design as needed), share solution
People with kidney disease need food that is:
Low protein and low sodium (salt)
A set of exclusive rights given by the federal government to the inventor of the device, substance, or process. Helps engineers make a profit.
Patent
The chance that an action or event could result in something unfavorable happening, such as injury
Risk
The way something is formed, built, or organized
Structure
