Vocabulary
100
this structure is made of solid pieces and strong material
What is a solid?
100
these forces come from the outside of the structure
What is external forces?
100
this is the effect of gravity on a structure
What is a static load?
100

This is when forces such as weather or human use, constantly wear on a structures stability.

What is structural fatigue


200
The Eiffel Tower in Paris, France is an example of this structure
What is a frame?
200
this external force acts on all structures all the time
What is gravity?
200
this is a force that moves or changes while acting on the structure
What is a dynamic load?
200

This is a measure of the amount of matter that something has/is.

What is mass

300
This structure is moulded into shape that provides strength and stability.
What is a shell?
300
this force is caused by one part of a structure acting on other parts of a structure
What is an internal force?
300
This is a force that pushes in opposite directions
What is shear?
300

This is what it is measured when gravity acts on a mass

What is weight

400
this is any push or pull
What is a force?
400
this is a force that pulls
What is tension?
400
this is the force that twists
What is torsion?
400
Magnetic force and gravity are these types of forces.

What is a contact force

500
an igloo is an example of this type of structure
What is a shell?
500
this is a weight that presses down
What is compression?
500
this force allows scissors to work
What is shear?
500

This is the formula for calculating the force of gravity
