1. Stability
1.1. Center of Gravity
1.1.1. The center is gravity is a point where most of the weight lies and the center of gravity is where it's most balanced so a lower center of gravity would be more stable that a high center of gravity
1.1.1.1. hockey player
1.1.1.2. Football Player
1.2. Wieght
1.2.1. The weight of an object affects the stability of an object because the more heavy something is the harder it will be to move so it can withstand things like wind
1.2.1.1. Heavy
1.2.1.2. Light
1.3. Width of base
1.3.1. The width of the base affects the stability because a wide base makes it so that there is a lot of space for the structure to be supported by
1.3.1.1. Pyramind
1.3.1.2. Cn Tower
2. Types Of Structures
2.1. Solid
2.1.1. A non-hollow structure that is one of the most common and stable types of structures
2.1.1.1. Pyramid
2.1.1.2. Dam
2.2. Shell
2.2.1. A shell is meant to contain something within the shell and is one of the more fragile types of structures
2.2.1.1. Egg
2.2.1.2. Water Bottle
2.3. Frame
2.3.1. A frame is more used as an inner layer to a structure and make it more stable
2.3.1.1. House Frame
2.3.1.2. Car Frame
2.4. Combination
2.4.1. A combination structure is exactly what it says a combination between the 3 types for example there could be frame and shell or a frame and solid and etc...
2.4.1.1. House (Frame+Solid)
2.4.1.2. Plane (Shell+Frame)
3. Loads
3.1. Dead load
3.1.1. The dead load is the permanent force that does not change. It can also be defined as the struture's weight itself
3.1.1.1. Bridge
3.1.1.2. table
3.2. Live load
3.2.1. The live load is the non-permanent and moving force that is acting on the dead load
3.2.1.1. truck
3.2.1.2. bicycle
3.3. Dynamic load
3.3.1. The dynamic load is the force caused by nature and can affect the its overall weight with live and dead load together
3.3.1.1. Wind
3.3.1.2. Water
3.4. Static Load
3.4.1. A static load is a structure that can support itself
3.4.1.1. Elevator
3.4.1.2. Bridge
4. Internal Forces
4.1. Tension
4.1.1. Tension is the force of being pulled and stretched
4.1.1.1. tension
4.1.1.2. tension
4.2. Torsion
4.2.1. Torsion is the force of being twisted
4.2.1.1. Twisting a sponge
4.2.1.2. torsion
4.3. Compression
4.3.1. Compression is the force of being pushed together
4.3.1.1. compression
4.3.1.2. compression
4.4. Sheer
4.4.1. Sheer is the force of 20 things going in the opposite direction of each other
4.4.1.1. Tearing paper
4.4.1.2. Rubbing hands
5. External Forces
5.1. Gravity
5.1.1. Gravity affects everything on earth, it is what weighs everything down so everything doesn't float like in space. The gravitational pull is determined by the mass of the object so objects like the sun have a much stronger gravitational pull
5.1.1.1. gravity
5.1.1.2. Low Gravity
5.2. Wind
5.2.1. Wind can be a very soft force or a very strong force that blows against an object and if powerful enough, will knock it over or possibly destroy it.
5.2.1.1. Light wind
5.2.1.2. Huricane
5.3. Water
5.3.1. Water, like wind can be heavy or light, but unlike wind the more water you put on something the heavier the water will be and it has the strength to cut through metal
5.3.1.1. Tsunami
5.3.1.2. Rain
5.4. Fire/heat
5.4.1. Heat or fire will act upon the structure depending on what it is, it is usually used for molding or melting metal or plastic. Fire is also used to burn through wood very quickly if there is a need for that.
5.4.1.1. fire
5.4.1.2. Blow Torch
6. Applying Forces
6.1. Point of Application
6.1.1. Point of application is the spot where force is being applied wither its internal or external force
6.1.1.1. point of application
6.1.1.2. point of application
6.2. Plane of Application
6.2.1. Plane of application is the force that's applied to an object to make the object move from another spot
6.2.1.1. plane of application
6.2.1.2. plane of application
6.3. Magnitude
6.3.1. Magnitude is the speed of the force that is applied to an object
6.3.1.1. Fast
6.3.1.2. Slow
