Engineering Design Process
An early version of a design, often used for testing is called a __________.
Prototype
Name and define the two main types of forces in bridges.
Compression: a force that tends to shorten objects
Tension: a force that tends to lengthen objects
This force opposes the direction of movement.
Drag
Emma is collecting information about the problem she wants to solve.
Research
Planes experience two pairs of forces. Lift and Weight make up one pair; ______ and ______ make up the other.
Drag, Thrust
This step follows brainstorming and involves looking into materials, permits, and economics.
Plan
___________ happens when an object experiences more tension than it can handle.
Snapping
Airplanes experience these four forces.
Lift, Drag, Weight, Thrust
An engineer notices that their phone keeps running out of battery when it gets too cold, and they decide to build a better battery.
Ask
A higher temperature usually leads to a __________ pressure.
Higher
Name all the steps of the engineering process.
Ask, Research, Imagine, Plan, Create, Test (and Evaluate Prototype), Improve (and Redesign)
___________ happens when an object is compressed beyond what it can withstand.
Buckling
State Newton’s First Law.
An object at rest tends to stay at rest; an object in motion tends to stay in motion.
Izzy has finished all her research on a problem and is thinking up solutions.
Imagine
__________’s Principle states that fluids travel faster when in contact with a surface.
Bernoulli
The engineering design process is _________, meaning that it is repeated many times.
Iterative
Steel is a combination of carbon and _________.
Iron
State Newton’s Third Law.
Any action has an equal and opposite reaction.
Joaquin adds extra cushions to the inside of his group’s bottle rocket after the egg cracked during their test.
Improve (and Redesign)
Steel is ________, which means it can bend somewhat without breaking.
Ductile
Limitations, restrictions, or challenges to a design are called ____________.
Constraints
This type of bridge relies mainly on compression forces.
Arch (bridge)
If an airplane stays at the same altitude and weighs 10 N, how much lift is it generating?
10 N
An engineering student throws a paper airplane they designed and noticed that it didn’t travel as far as they meant for it to go.
Test (and Evaluate Prototype)
In step 7 of the EDP (Improve and Redesign), test data is used to make ________ of the design. Hint: think “new versions”
