The best chances of a structure being stable come from having a low centre of gravity and this?
What is a wide, stable base?
100
This horizontal structure is designed to support a load?
What is a beam?
100
This structural failure is the 2nd most common type of structural failure to occur.
What is bad/faulty construction?
100
The ability to remain in a balanced position when forces act on it.
What is stability?
100
This type of beam is only supported at one end.
What is a cantilever?
200
When part - or all - of a structure is unable to support its load.
What is structural failure?
200
This support structure looks like the top half of an egg, but it is not fragile like an egg at all....
What is a dome?
200
These structural supports that strengthen beams are identical, except for where they support the beam.
What is a tie and a strut?
200
This type of structural failure is the most common.
What is bad/poor design?
200
The truss is a network of beams made in a series of this shape.
What are triangles?
300
The structural failure that occurs when a builder chooses to use lower-quality or inappropriate materials to save money.
What is poor/faulty construction?
300
These 2 structural supports are not beams: they are rounded.
What is an arch and a dome?
300
The point around which the structure's mass is balanced in all directions?
What is centre of gravity?
300
This is the force at play when you have to put on a heavy backpack and have to adjust your stance to keep your balance.
What is centre of gravity?
300
This type of structural failure occurs when an architect for a bridge fails to account for the fact that several heavy trucks will pass over the bridge at the same time. The result: if too many trucks cross over the bridge at the same time, the bridge will crack under the load pressure.
What is poor/bad design?
400
The structural failure that occurs when the soil that a structure is built on shifts or loses its firmness.
What is Foundation Failure/Fault Foundation?
400
This type of beam is especially strong when you fold ridges into it.
What is corrugation?
400
To keep from tipping over, this is where should the centre of gravity be for a given object.
What is low/low to the ground?
400
Re-inforced concrete is an example of this type of beam.
What is a rebar?
400
This type of structural failure occurs when a teenager sits in/on a toy intended for a small child.
What is an extraordinary load?
500
In which types of situations would an arch be a better structural support than a beam?
What is when putting in a long beam is not practical?
500
These 3 supports can be used to strengthen a beam.
What is ties, struts and gussets?
500
The 4 ways to strengthen a beam
What is use strong material, use an I-beam, use corrugation and use a re-bar?
500
The reason why is standing up in a canoe is dangerous.
What is it moves the centre of gravity, causing it the potential to tip over/lose its balance?
500
The difference between a cantilever and a beam.
What is both are beams but a cantilever is a beam re-inforced/supported only on one end?
