Definination: Manufactored Structures

Back 3

These types of structures are formed by man in the world

Front 4

Ex: Manufactored Structures

Back 4

Roller coaster, houses, buildings, apartments, school, binder, etc...

Front 5

What is a Frame Structure?

Back 5

A frame structure is a type of structure in which a skeleton of materials supports the weight of the other parts.

Front 6

Ex: Frame Structures

Back 6

goal posts, girder bridges, roller coasters

Front 7

what is a mass structure?

Back 7

it is made by piling up of some materials. It can be made by nature or by man

Front 8

Ex: Mass structure

Back 8

pyramids, snow fort, bricks, mountain, great wall of china, etc..

Front 9

What is a shell structure?

Back 9

a structure that obtains strength from a thin, carfully shaped outer layer of material. this requiers no internal frame

Front 10

Ex: Shell structures

Back 10

Igloo, egg, etc..

Front 11

what is a arch structure?

Back 11

This is made from wedge shaped peices that will lean against eachother. The middle peice is called the key stone, holds the whole thing together, and is usually bigger than the rest. It is the last one to be put in the structure. It has been argured that an arch strucure is not a different catagory than the rest and should be in a different catagory.

Front 12

Ex: Arch Structures

Back 12

Bridges, door, windows, delicate arch in uhta.

Front 13

some ways to make it more aesthetics pleasing

Back 13

Nature, art, make it look good, marble, gold, shiny, symmetrical, original, colors, textures, etc...

Front 14

Definition of force

Back 14

A push or pull that tends to cause an object to change its movement or shape

Front 15

Definition of Mass

Back 15

Amount of matter in an object

Front 16

Definition of weight

Back 16

The amount of force that gravity exerts on an object on earth

Front 17

Definition of Gravitational force

Back 17

the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface

Front 18

Definition of force meter(spring scale)

Back 18

Piece of equipment containing a spring, used to measure forces

Front 19

Definition of Balance

Back 19

Same weight on each side of the object

Front 20

Definition of Newton(N)

Back 20

Unit for measuring force

Front 21

Definition of Kilogram

Back 21

One thousand grams, a measure of weight

Front 22

Definition of Squeezing

Back 22

This is when you push something together and you might get it smaller

Front 23

Definition of Stretching

Back 23

Tension is when you stretch something so you might get it longer

Front 24

Definition of bending

Back 24

When a straight material bends on side stretches and the other squeezes

Front 25

Definition of sliding

Back 25

Shear is a force that makes part of the material to slide past each other in opposite directions

Front 26

Definiton of twisting

Back 26

Torsion is when you twist a material

Front 27

GOOD LUCK!!!!!!!!!!!

Back 27

IT'S EASY!!!!!!!!!!!
