Types of Structures
The weight carried by a structure.
What is a load?
The main purpose of an object or structure.
What is function?
The amount of matter in something.
What is mass?
Stresses that act on a structure from the outside.
What are external forces?
A material breaking at a point due to force acting on it in two opposite directions
What is shearing?
One of the 3 kinds of designs of a structure that can be made by piling up similar materials into a shape or design.
What is a mass structure?
The study how something looks.
What is aesthetics?
The standard unit of force that measures the amount of gravity pulling down on a object.

Structures not made by people, such as feathers and sand dunes.
What is a natural structure?
The extra strength that lets structures carry larger loads than they are said to be able to carry.

This is a picture that uses arrows to show the strength and direction of one or more forces.
What is a force diagram?
This is a changeing or a non-permanant force acting on a structure.
What is a live load?
The point on which the force of gravity acts directly is called the_____________
Centre of Gravity
