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.
At frank slides, there was a massive amount of compression on the mountain from its weight. Eventually a side of the mountain broke off in a landslide due to this type of failure
What is shear failure?
A staple sitting on a desk is an example of a
What is a live 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?
Car bumpers and sheet metal used in cars are designed to do this in a collision.
What is fail?
This is the device used to measure the weight of an object
What is a spring scale
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 is carefully 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?
In our paperclip experiment, we bent the paperclip until it got warm and broke apart due to this.
What is metal fatigue?
Compression can cause a material to
What is a bend or buckle
The advantage to this type of structure is that it 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)
Which direction is the box moving in this force diagram?
