Types of Structures
This can be classified as a push or a pull
What is a force?
Lego pieces have these types of joints.
What are rigid interlocking shapes.
A measure of the amount of matter in material.
What is mass?
When you kick a soccer ball, you produce this type of internal stress on the ball.
What is compression.
Eventually a side of the mountain broke off in a landslide due to this type of failure
What is shear failure?
Laying on a bed of nails is possible because the weight of your body can be spread out on each nail. This demonstrates this method of design we talked about it class.
What is distributing the load.
This includes the weight of the structure itself and other permanent parts of the structure
What is a dead load?
The shape, colour, texture, etc. of a structure is this type of component of a structure.
What is aesthetic.
This is the correct term for the force of gravity acting on a structure.
What is weight
This type of internal stress occurs within a rope during a game of tug-of-war
What is tension?
When the center of gravity goes outside of a base this is what happens to the structure
What is fall over?
An arch is a good design to direct the forces along angled components. The arch is held together by this central stone called this
What is the keystone
This is anything with a definite size and shape, which serve a definite function.
What is a structure?
Layers of different materials pressed or glued together are this type of material.
What are laminations?
This is the standard unit of force.
What are Newtons?
Internal stresses can change the shape of a structure. This change of shape to a structure is called a ...
What is deformation?
In a boat's outboard motor, the propeller is held to the engine with a shear pin. This pin breaks if the propeller gets tangled in the weeds. Why is the shear pin designed to fail?
What is to prevent further damage to the engine.
This is the strongest shape
What is a triangle :)
These types of structures are strong and hollow and have a thin outer layer that has a curved shaped to provide strength.
What is a shell structure?
Where a structure's parts are held together.
What are joints?
In order to properly describe a force acting on a structure, you would need these 2 qualities of the force
What are direction and size (magnitude)?
When bending a material, these two internal stresses are acting on the material
What are compression and tension?
When you continually bend a paperclip until it got weak and almost breaks apart.
What is metal fatigue?
In order to direct the force of a trianglar structure along angled components, these 2 features are used.
What are struts and ties? (ties in tension/ struts in compression)
The advantage to this type of structure is that it is mostly solid and holds itself together by its own weight.
What is a mass structure?
Glues are a type of this type of joint.
What are rigid adhesive joints?
What is the acceleration due to gravity on Earth? Include units!
What is 9.81 m/s2 (or 10 m/s2)
This internal force occurs when you twist the material by turning the ends in opposite directions.
What is torsion?
During an intense game of tug-of-war, the rope withstood all the forces acting on it. The rope demonstrated this type of strength.
What is tensile strength (withstanding tension)
This force is always acting in the opposite direction of an applied force.
What is friction?
