The Great Classi‑FICATION
Name the 4 types of structures that we have learned about in class:
Shell, solid, frame, and combination
The stability of a structure depends mostly on this.
centre of gravity
A structure that can be divided into equal sides is considered to be:
symmetrical
Shape does NOT need to be considered when choosing materials. (true or false)
true
What is the name for the testing that make sure that a product meets the level of quality (standards) so it can be sold to consumers.
Performance testing
Structures are often classified as frame, shell, solid, or combination, what other way can they be classified?
natural or manmade
A push or pull that changes an object’s shape or direction.
Force
symmetrical structures have better ___________.
stability
Manufactured flaws and poor aesthetics are two main reasons structures may fail. (true or false)
false
What is the term for designing structures using limited resources or time.
Designing for efficiency
What is it called when a structure uses more than one classification?
combination
What is the strength of a force called?
Magnitude
Designers care about this because it helps increase sales.
aesthetics
Performance testing and risk management are two technical requirements that help ensure structures are safe. (true/false)
true
Aesthetics are subjective, depends on companies preferences. (true or false)
false
This type of structure is also called a mass structure and is usually made of strong materials.
Solid structure
This tells you where the force is coming from or going.
Direction
This field focuses on designing products that maximize comfort and reduce injury for humans.
Ergonomics
This happens when a product is designed with a planned lifespan.
planned obsolescence
A structure becomes less stable when it increases in ___________.
height
This type of structure has a skeleton‑like support system.
Frame structure
This is the exact spot where the force meets the structure.
point/plane of application

1. Cost
2. Availability
3. Ability to manufacture
4. Strength and durability
5. Sustainability
6. Climate
7. Aesthetics
8. Life of the material
9. Handling and storage

Too heavy of a ______ can cause structures to fail.
load
Having a ________ base ensures a more stable structure.
wide/large
