What is the definition of a STRUCTURE?

A) A supporting framework, with a definite size, shape, and purpose, that holds a load

B) A series of increasingly important jobs that someone can do within a company

C) A flexible loop that is made of rubber and used to hold things together

D) None of the above

What is the definition of a LOAD?

A) The amount of work that a person carries or is expected to carry

B) The amount of authorized work to be performed by a machine, a group, a department, or a factory

C) Both a and b

D) A weight that a structure must support

What is the definition of STABILITY?

A) The quality or state of not being firmly fixed in position

B) Anything that precedes something similar in time

C) The ability to maintain balance and stay fixed in one spot

D) Above average in size or number or quantity or magnitude or extent

What is a STRUT?

A) To walk in a pompous manner

B) Is a beam or bar used to support heavy loads. A strut is used in a structure so that it isn't compression to the part where it clenches

C) The intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment

D) A type of food served in France

What is the definition of TRUSS?

A) A frame that uses rafts, rafters, posts, and struts to support a roof, bridge, or other structures

B) Is a a resting torpid condition with suspended growth and reduced metabolism

C) The buying and selling of goods, especially on a large scale, as between cities or nations

D) Of or belonging to the family Felidae, which includes the lions, tigers, jaguars, and wild and domestic cats

What is the definition of CENTRE OF GRAVITY?

A) The place in a system or body where the weight is evenly dispersed and all sides are in balance. An example of centre of gravity is the middle of a seesaw

B) Not clearly or explicitly stated or expressed

C) A traditional, typically ancient story dealing with supernatural beings, ancestors, or heroes that serves as a fundamental type in the worldview of a people, as by explaining aspects of the natural world or delineating the psychology, customs, or ideals of society

D) None of the above

TRUE or FALSE: The definite shape and size of a structure refers to the arrangement of atoms in a molecule of a chemical compound

True

False: The definition of a structure also says that structures have a definite shape and size. The word definite means clear. For example, the CN Tower is a very narrow but tall structure

TRUE or FALSE: Do all structures have a purpose?

True. All structures have a purpose. A purpose is the reason for which something is created or exists. A house for example, has the purpose of keeping people safe from the outside

False

TRUE or FALSE: Can all structures hold a load?

True. All structures are designed to hold a load. A load is a weight or source of pressure

False

What are 2 structures that can carry a big load?

A) dump trucks & skyscrapers

B) Bridges

C) Both a) & b)

D) None of the above

What are man-made structures?

A) It means a human built the structure. Examples of man-made structures are computers, buildings, and doors

B) Any of a class of organic compounds characterized by an oxygen atom attached to two carbon atoms

C) A crisp cake of batter baked in a waffle iron

D) A table on a map, chart, or the like, listing and explaining the symbols used

What are natural structures?

A) The part of the elbow where the ulnar nerve passes by the internal condyle of the humerus, which when struck causes a peculiar, tingling sensation in the arm and hand; crazy bone

B) Are solids in our environment that were not made by humans. This means that anything in our environment that animals make or that grows naturally are natural structures. Examples of natural structures are bee hives, rocks, and plants. These structures grow without humans making them

C) Property or other assets pledged by a borrower as security for the repayment of a loan

D) A brand of pop

What are unstable structures?

A) A type of bubble wrap

B) Freeze dried food that comes in a can

C) Means the structure will fall over because it can't keep its balance

D) The game Jenga

How can you change building materials to make them stronger?

A) By adding more water

B) By adding a sticky type of glue

C) By adding layers, twisting/braiding, and folding

D) None of the above

Can you think of a building material that is commonly layered, twisted or folded?

A) Rope in an elevator shaft is commonly twisted and braided

B) Wi-Fi

C) A pretzel

D) A candy wrapper

TRUE or FALSE: Triangles are so strong because they have 3 angles that cannot get bigger, unless the triangle is broken

True. When a force or load pushes on one of the angles, it will not bend or move. All of the force or load is spread out into all 3 angles, which makes it unlikely that the triangle will break

False

What structures are made from trusses?

A) Truss frames are used in bridges and homes. If your house has a peaked roof, it uses a truss, or several trusses

B) Plumbing

C) A picture frame

D) Companies and businesses

TRUE or FALSE: Beam, truss, arch, and suspension are types of bridges

True. Go over the use of each one and material used in your binder

False

What are some bridge failures?

A) the bridge is not able to support the load it was built to support

B) The materials used to construct a bridge do not hold up over time

C) Earthquakes can damage structures, such as bridges

D) A support post is damaged (sometimes by vehicles, trains, or boats)

E) All of the above

TRUE or FALSE: We must plan for the elements that bridges have to withstand

True. To withstand means to hold up against. Planning for natural events such as earthquakes is possible by trying to build a structure in areas where these events do not happen often. Using strong materials such as steel is also important, but we must remember that these materials weigh quite a bit and the bridge must be able to hold up the weight of the materials used to build it

False
