This can be classified as a push or a pull 

What is a force?

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

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. 

200

This includes the weight of the structure itself and other permanent parts of the structure

What is a dead load?

200

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

What is weight

200

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

What is tension?

300

This is anything with a definite size and shape, which serve a definite function.

What is a structure?

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 is the strongest shape

What is a triangle :) 

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

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?

500

The advantage to this type of structure is that it holds itself together by its own weight. 

What is a mass structure?

500

What is the acceleration due to gravity on Earth? Include units! 

What is 9.81 m/s2  (or 10 m/s2)

500

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

What is torsion?

500

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

What is friction?
