Structures & Forces

1. The dead load is a structure that can hold something up. For example, a live load like a bridge holding up a car.

2. Static loads

2.1. It's caused by the force of gravity

3. Live load

3.1. The live load is a force that acts on the structure. The one that gets supported by the dead load is usually called the live load

4. For example, pulling a rubber band

5. Compression

5.1. For example, sitting on a chair

6. Dynamic loads

6.1. These forces act on a part of a structure. For example, wind hitting the sail of a boat.

7. Internal forces

7.1. Tension

8. Loads

8.1. Dead load

9. Forces that act on structures

9.1. External forces

9.1.1. Direction

9.1.1.1. Where the force is applied for example,the up down left or right.

9.1.2. Plane of application

9.1.2.1. The angle of where the force is applied for example 90 degrees

9.1.3. Point of application

9.1.3.1. Where the force is applied.For example, the base, top or middle part of the structure.

9.1.4. Magnitude

9.1.4.1. How strong the force being applied is.

10. Purpose- It keeps people safe from attackers a long time ago

10.1. Function-Moat,towers,support buildings and other parts that make a castle stronger

11. Form- it looks like a giant tower with small walls attached to it

12. Function- it allows people to live in cold places and doesn't melt because it is made of ice

13. Form- It looks like a dome made out of ice blocks that look like bricks. There is a space that leaves a hole so that people can get inside

14. Torsion

15. Solid

15.1. Castle

16. Eiffel Tower

16.1. Form- it has the same design as cardboard. For example, cardboard is corrugated to make it stronger.

16.2. Purpose-it's a great tourist attraction. The designer made the base wide so that it would be strong and that people could go inside without the structure collapsing.

16.3. Function- it has an elevator on the inside to carry people to the top. There are also stairs.

17. Purpose- people who live in cold places build igloos for shelter

18. Solid

18.1. A solid structure is one whole piece without any separate parts

18.1.1. An example would be an ice berg

19. Shell

19.1. Usually, A shell structure is hallow. They are stronger than they look.

19.1.1. An example would be an igloo

20. For example, twisting a towel dry

21. For example, ripping paper

22. Shear

23. Purpose, form, and function of the structures

23.1. Frame

23.2. Shell structure

23.2.1. Igloo

24. Different Types Of Structures

24.1. Frame

24.1.1. A frame structure is made of different parts that are put together

24.1.1.1. An example of an frame structure would be an Eiffel Tower.
