May the Force be with you
This is a unit for measuring force, named after a scientist who may not like apples
Newton
joint
Ms. Harasymuk walking her dog Rocket over a pedestrian bridge
Dynamic
Twisting is this type of force.
Torsion
The strongest of all the shapes
triangle
Gravity is an example of this type of force, which is applied to a structure by something else.
external force
an example of this includes knees, elbows, and hinges
movable joints
a stampede of grade 7s running down a staircase
dynamic
corrugation
type of bridge that hangs between 2 ends, often supported by cables
suspension
To make a structure more stable and prevent it from tipping, engineers try to make this part of the structure wider
base (foundation, bottom)
they are rigid to prevent any movement
fixed joints
Ms. Bruno's collection of books that she never reads sitting on her bookshelf
static
"I'm hungry, I'm tired, my feet hurt" said this structural stress that causes weakening over time.
Fatigue
roof type that provides drainage for rain and snow
gable
Shear
smooth surfaces have less of this, like skates on fresh ice, and rough surfaces have more of it, like trying to stop on ice
friction
a gust of wind causing a building to sway
dynamic
The 4 main types of forces that cause failure.
Compression, torsion, tension, shear
this imaginary point in an object is where the downward force of gravity acts
centre of gravity
The three things that determine the actual effect on a force on a structure.
Magnitude (size), Direction, Location
examples of joints that rely on bonding, like the welding that holds up your stool, and the glue that definitely wouldn't
adhesives, welds
A Dead load
static
This is the term for a change in shape in a structure because it can't resist the load acting on it.
Deformation
structural component that can carry large loads because the force is evenly distributed and sent back int the foundation (hint: contains a keystone)
