Structures by Mind Map: Structures

1. Types of structures/form

1.1. Combination Sturctures

1.1.1. A structure that is made up of all the other structures combined. for example a house for example a bed

1.2. Shell Structures

1.2.1. a strong hollow structure that can contain things inside for example a water bottle for example an igloo

1.3. Solid Structures

1.3.1. a structure that is solid all the way through for example a sand castle for example a rock

1.4. Frame Structures

1.4.1. a structure that is fastened together for example a car for example your skeleton

1.5. Form is the basic shape of the structure

1.5.1. For example, diamonds are solid all the way through.

1.5.2. For example, a book is made of many papers fastened together.

2. Forces

2.1. Internal Forces

2.1.1. A force that acts on an object on the inside For example, a person pressing down on a table Another example is when someone bend a book

2.1.2. Tension Tension is a stretching force for example when you stretch a rubber band so it expands for example when you stretch your body

2.1.3. Torsion Torsion is a twisting force for example when you twist or turn your body around for example when you twist clay

2.1.4. Compression Compression is a force when you squeeze or press the objects together for example when you flatten clay for example when you put a book on your head, the book is pressing down on your head

2.1.5. Shear shear is a force that pushes in opposite directions, or bending it for example when you do a back bend for example when you bend a ruler

2.2. External Forces

2.2.1. load The forces' effect acting on the structure For example, a chair Another example is a child dynamic load The force that move or change while acting on the structure static load A structure been effected by gravity, and the forces of it doesn't move or change

2.2.2. gravity The natural force of attraction between two objects For example, when you bounce a ball, the ball will be pulled down by gravity. For example, when a person jump, he or she will always be pulled down by gravity.

2.2.3. A force that acts on an object from the outside For example, an earthquake. For example, rainfall, glaciers, etc.

2.3. Any push or pull that acts on structures

2.3.1. For example, a cat pulling a ball

2.3.2. For example, a person pushing against a desk.

3. Function

3.1. What the structure does.

3.2. For example, a bridge's function is for people to cross a body of water

3.2.1. For example, a book's function is for people to read.

3.3. strength

3.3.1. The ability of an object to withstand forces for example when a chair holds a person, while they sit on it for example when we hold our binders

4. Describing forces

4.1. point of application

4.1.1. the exact location where a force meets the structure for example when a basketball hits a person , the point where the basketball hit the person is the point of application, like the side of the upper leg. for example, when water hit a person, the point where the water hit is the point of application, like the palm a hand.

4.2. plane of application

4.2.1. the side of a structure that's been effected by force. for example, a ball that's been hit with 90 degrees for example, a golf ball been hit with 180 degrees angle

4.3. direction

4.3.1. Which direction the force meet the structure: a push or a pull for example a person pushing a cart for example, a person pulling a rope.

4.4. magnitude

4.4.1. How strong or weak the force is. for example, gently tap a table, and the table is not been effected, the magnitude is low. For example, pushing a desk really hard, the desk moved over, the magnitude is high.
