Design Process
What is the first step in the engineering design process?
Identify the problem
What are criteria?
What the design must do
Which simple machine is a slanted surface?
Inclined plane
Which law is F = ma?
Newton’s Laws
Which impact deals with money and jobs?
Economic
What step comes after brainstorming solutions?
Build a prototype
What are constraints?
Limits (time, cost, materials, etc.)
Which machine uses a rope and wheel?
Pulley
Which law deals with circuits (voltage, current, resistance)?
Ohm’s Law
Which impact deals with people and society?
Societal
During which step do you check if your design works?
Test
Is “must hold 20 pounds” a criteria or constraint?
Criteria
What simple machine is found in a wheelbarrow?
Lever (also wheel & axle acceptable)
Which law explains pressure being transmitted evenly in fluids?
Pascal’s Principle
Which impact deals with nature and environment?
Environmental
Why is the improve step important?
To fix problems and better meet criteria
Is “budget of $10” a criteria or constraint?
Constraint
Which machine splits or cuts objects?
Wedge
Which law explains airplane lift?
Bernoulli’s Principle
Creating clean water systems is what type of impact?
Environmental
You test a bridge and it collapses. What step comes next AND why?
Improve; to fix what failed and meet criteria
A design must be waterproof but you only have cardboard. Identify one criteria and one constraint.
Criteria = waterproof; Constraint = materials (cardboard)
You need to move a heavy box into a truck. What is the BEST simple machine and why?
Inclined plane; reduces force by increasing distance
Why does faster-moving air create lift on a wing?
Faster air = lower pressure → lift (Bernoulli)
A new factory creates jobs but increases pollution. Name TWO impacts.
Economic + Environmental
