The human skeleton is a structure
True
What external natural force is a strong gust of wind that moves in a twisting motion?
Tornado
What is the pushing force called?
Compression
How do you measure structural efficiency?
What a structure can hold divided by its weight
I am a type of structure that is hollow on the inside and hard on the outside. Examples of me would be a dome and an egg
Shell Structure
A tornado is an example of an internal natural force
False (external!)
Name an external natural force that involves water
Hurricane, tsunami, thunderstorm...
What is the pulling force called?
Tension
What is the magnitude of a 50kg person sitting on a chair?
50kg or 500N
I am a type of structure that has a completely solid interior and exterior. Examples of me would be a brick and a rock.
Solid Structure
Torsion is one of the 4 types of forces
True
What is an external natural force we can potentially face in Winnipeg?
Tornado, Snow, flood...
What is the twisting force called?
Torsion
What direction is the effort going when a 50kg person is sitting on a chair? (effort = person)
Down
I am a type of structure that has rows and columns. Examples of me would be a house and a skeleton.
Frame Structure
Wood is a material that is strong against hurricanes
False
What external natural force was devastating California recently?
Wildfires
What is the sliding force called
Shear
Where is the point of application when a 50kg person is using a pull-up bar?
Where their hands touch the bar.
I am the place that you directly put effort on a structure.
Point of application
We calculate structural efficiency by dividing the mass of a structure by the maximum mass supported
False (the other way around)
Name something you could do to a house to make it more resistant to a flood
Elevate it, give it eavestroughs, build it out of concrete/steel...
Name all 4 types of forces
Shear, tension, torsion, compression
50
I am the weight that you get your magnitude from when pressure is applied. What am I called?
Effort
