This can be classified as a push or a pull 

What is a force?

100

Lego pieces have these types of joints.

What are rigid/fixed, interlocking shapes? 

100

A measure of the amount of matter in material.

What is mass?

100

When you kick a soccer ball, you produce this type of internal stress on the ball. 

What is compression. 

100

This is the strongest shape.

What is a triangle?

200

This structure includes an outline of materials to make it strong.

What is a frame structure?

200

A door hinge would be an example of this type of joint. 

What is a flexible/movable, fastener joint? 

200

This type of device would measure the mass of an object.

What is a balance scale?

200

This type of internal stress occurs within a rope during a game of tug-of-war

What is tension?

200

Car bumpers and sheet metal used in cars are designed to do this in a collision.

What is fail from buckling/being crushed in the front? This absorbs some of the momentum from the impact.

300

An example of this structure would be a water bottle.

What is a shell structure?

300

Layers of different materials pressed or glued together are this type of material.

What are laminations?

300

This is the standard unit of force.

What are Newtons?

300

Internal stresses can change the shape of a structure.  This change of shape to a structure is called a ...

What is deformation?

300

This force is always acting in the opposite direction of an applied force.

What is friction?

400

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?

400

The name where a structure's parts are held together.

What are joints?

400

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)?

400

When bending a material, these two internal stresses are acting on the material

What are compression and tension?

400

In our paperclip experiment, we bent the paperclip until it got warm and broke apart due to this. 

What is metal fatigue?

500

The disadvantage to this type of structure is that it is difficult to move. 

What is a mass/solid structure?

500

Glues are a type of this type of joint.

What are rigid/fixed, adhesive joints?

500

This is the correct term for the force of gravity acting on a structure.

What is weight?

500

This internal force occurs when you twist the material by turning the ends in opposite directions. 

What is torsion?

500

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?
