Structures and Forces by Mind Map: Structures and  Forces

1. Forces

1.1. Internal Forces

1.1.1. A force that affects only the inside of a structure

1.1.1.1. Torsion

1.1.1.1.1. A type of force that twists an object/structure

1.1.1.2. Shear

1.1.1.2.1. A type of internal force that pushes a structure in opposite directions

1.1.1.3. Tension

1.1.1.3.1. A type of internal force that stretches a structure

1.1.1.4. Compression

1.1.1.4.1. A type of internal force that squeezes/presses a structure together

1.2. External Forces

1.2.1. A force that only affects a structure on the outside

1.2.1.1. Load

1.2.1.1.1. A external force that acts on a structure

2. Structures

2.1. Form

2.1.1. Basic shape of a structure

2.1.1.1. Shell Structure

2.1.1.1.1. A structure that is hollow on the inside

2.1.1.2. Combination Structure

2.1.1.2.1. A structure that contains a mixture of the other type of structures.

2.1.1.3. Frame Structure

2.1.1.3.1. A structure that is made of parts fastened together

2.1.1.4. Solid Strucure

2.1.1.4.1. A structure that is solid all the way through

2.2. Function

2.2.1. What the structure does/what is it used for

2.2.1.1. Example; The function of this chair is carrying the weight of people or objects that are going to be siting or placed on it.

2.2.1.2. Example; The function of this table is to hold things that will be placed onto it.

2.3. Center of gravity

2.3.1. Where the balance point and where most of the weight is on a structure

2.3.1.1. Image

2.3.1.2. Image

2.4. Effects On Structures

2.4.1. Point of App

2.4.1.1. Exact location where the force meets the structure

2.4.1.1.1. Example; This person is pushing this box exactly near the middle left of the box.

2.4.1.1.2. Example; This person is applying the force (poke) exactly on the top of the left arm.

2.4.2. Magnitude

2.4.2.1. Measure of how strong a force is

2.4.2.1.1. Example; The press is pressing down on the car with a high magnitude. (very strong)

2.4.2.1.2. Example; This person has a high magnitude in his punching.

2.4.3. Plane of Application

2.4.3.1. side of a structure affected by a force

2.4.3.1.1. This is an example of plane of application because it shows "panels" that show the sides of the person where a force can be applied. And the plane of application is a side which an applied force passes through.

2.4.3.1.2. This image is of a person, but it shows the sides of which a force can be applied to.

2.4.4. Direction

2.4.4.1. which way the force is applied to the structure

2.4.4.1.1. This image shows a person pushing a pole, and pulling the pole. This shows the direction of which the person is pushing/pulling; left and right.

2.4.4.1.2. This is an image of a person pushing a big weight in the direction up.

2.4.5. Speed of Applicaton

2.4.5.1. How fast the force is moving towards the structure.

2.4.5.1.1. Example; This boy is running really fast towards the wall

2.4.5.1.2. Example; The ball is moving really fast away from the person who threw it.

2.4.6. Angle of Application

2.4.6.1. The angle on the structure where the force is put

2.4.6.1.1. Example; This wreaking ball is going to hit this wall at a 90* angle

2.4.6.1.2. Example; This person is going to kick the ball at a 90* angle
