Natural vs Manufactured
What is the main difference between natural and manufactured structures?
Natural structures are created by nature, while manufactured structures are built by humans using various materials.
What type of structure is a bridge that uses a framework of beams?
A frame structure.
What is lamination?
lamination is the process of bonding layers of materials together for strength and durability.
What is a rigid joint?
A joint that does not allow movement between connected parts.
What is one of the five essential things to consider when designing a structure?
Load capacity.
Give an example of a natural structure.
Examples include mountains, caves, and trees.
What is a shell structure? Give an example.
A shell structure is a thin, curved surface that provides strength; examples include eggs and domes.
Which material is typically used in knitting or weaving?
Textiles or fabrics.
Give an example of a mobile joint.
A hinge, like that on a door.
What does 'margin of safety' refer to in structural design?
It refers to the extra strength built into a structure to ensure it can handle unforeseen loads.
Name a manufactured structure that is commonly found in cities.
Buildings or bridges.
How does a mass structure support loads?
A mass structure relies on its weight to support loads, typically made of solid materials.
Name a property of composite materials.
They can be lightweight yet strong and resistant to corrosion.
How do rigid joints affect the stability of a structure?
They enhance stability by preventing movement at the joint.
On Earth, the mass of Joe is 35.6 kg and his weight is 356 N. On Jupiter, Joe weighs 899 N. What is Joe's mass on Jupiter?
35.6 kg
What is an advantage of using natural materials in construction?
They can be more environmentally friendly and sustainable.
What type of structure is a tent considered?
A frame structure.
What is a common use for woven materials in construction?
They are often used in reinforcing structures or as part of roofing systems.
Why might mobile joints be used in a structure?
They allow for movement and flexibility, which can help absorb forces and prevent damage.
What is a load in the context of structures?
A load is any force or weight that a structure must support.
Why might a manufactured structure be preferred over a natural one in certain situations?
Manufactured structures can be designed for specific needs and can be built to withstand certain conditions.
Explain how a composite structure combines materials.
A composite structure uses different materials together to achieve better strength, durability, or performance than using a single material alone.
Why are adhesives important in construction?
Adhesives bond materials together, providing additional strength and support at joints.
What is the main difference between rigid and mobile joints?
Rigid joints do not allow movement, while mobile joints enable movement.
Name two factors that affect the design of a structure.
Environmental conditions and material properties.
