Name that Structure
This is something with a definite shape and size that serves a purpose.
Structure
A __________ is a push or a pull on an object.
Force
This term describes what a structure is supposed to do.
Function
This property means a material can be stretched and will return to its original shape, like a rubber band.
Elasticity
Wind pushing on a skyscraper is this type of force: internal or external?
External force
This type of structure is made of many parts joined together, like a bicycle or a chair.
Frame Structure
This type of load is the weight of the structure itself and does not change.
Dead Load
This term describes how a structure looks and how it is built.
Design
This property means a material can resist being pulled apart.
Snow building up on a roof is this type of load.
Live Load
This type of structure is hollow, strong, and often lightweight, like an eggshell or a pop can.
Shell Structure
This type of load is temporary and can change, like people, vehicles, or wind.
Live Load
A structure is stable when it resists this kind of motion
Tipping, toppling, overturning
Engineers consider strength, mass, durability, and this “bendiness” property when choosing materials.
Flexibility
An arch pushes forces in these two directions.
Outward and downward
This structure type is made from solid materials, all in one piece or with no large hollow spaces, like a brick or a concrete dam.
Solid Structure
This internal force pulls a material apart, like a rope in a tug-of-war.
Tension
One simple way to increase stability is to make this part of the structure wider.
Base
Shear happens when parts of a material slide __________ each other.
Pass one another
A beam is this orientation of structural member (direction word).
Horizontal
Most real-world structures are not just one type; they use frame, shell, and solid all together.
Combination Structure
This internal force twists a material, like when you wring out a wet towel.
Torsion
Lowering this point of an object makes it more stable and harder to tip.
Centre of Gravity
Adding these triangular supports helps distribute forces and prevent failure in bridges and towers.
Trusses or braces
A tall tower with a very narrow base and high centre of gravity might have this problem in strong winds.
Tip over/be unstable
