1. Form and Function
1.1. Function
1.1.1. The function of the CN Tower is to entertain tourists and teach them about the CN Tower.
1.2. Form
1.2.1. The CN Tower is built to withstand heavy rain, lightning, hale, snow and high winds because it is made from strong materials like metal and wood.
2. External Forces
2.1. Force
2.1.1. A force applied to this structure is wind.
2.2. Direction
2.2.1. The direction of the force of wind is a push because it pushes against the Tower when it blows.
2.3. Magnitude
2.3.1. The magnitude is usually moderate but could be high or low depending on how hard the wind is blowing.
2.4. Plane of Application
2.4.1. The plane of application is 180 degrees.
2.5. Point of Application
2.5.1. The point of application is the sides because the wind usually comes from the right or left.
2.6. Force
2.6.1. Another force applied to the CN Tower is the snow.
2.7. Direction
2.7.1. The direction of the force is a push because the snow pushes down on the top of the CN Tower when it lands on it.
2.8. Magnitude
2.8.1. The magnitude of the snow is usually moderate depending on how much snow is falling
2.9. Plane of Application
2.9.1. The plane of application is 90 degrees.
2.10. Point of Application
2.10.1. The point of application is the top of the CN Tower because that is where most of the snow lands.
3. Internal Forces
3.1. Compression
3.1.1. The CN Tower experiences compression when people jump on the floor and when snow packs on top of the roof.
3.2. Shear
3.2.1. The CN Tower experiences shear when tornadoes occur because the top of it pulls one way and the bottom pulls another way.
3.3. Tension
3.3.1. The CN Tower experiences tension when there are high winds coming from both sides.
3.4. Torsion
3.4.1. The CN Tower experiences torsion when a hurricane or tornado comes by.
4. Purpose
4.1. The purpose of the CN Tower is to entertain people that visit this tourist attraction.
5. Type of Stucture
5.1. CN Tower is a combination stucture because it is hollow inside which makes it shell stucture, it was build with frame and it was made form soild materials make it part of a soild sturcture.
6. Centre of Gravity
6.1. The centre of gravity is in the middle of the CN tower. I think this is very important to CN tower because if the centre of gravity is too high, the tower won't be stable and if it is too low, it can't be stable too. So if the centre of gravity is in the middle, it can keep the tower stable.
7. Loads
7.1. Static loads
7.1.1. Dead load
7.1.1.1. The dead load is that anything on the CN tower that can use force cause by itself.
7.1.2. Live load
7.1.2.1. The live load is that the peoples or the other things that is not on the CN tower can cause by itself.
7.2. Dynamic loads
7.2.1. The dynamic load is that like if I and my father sand inside the CN tower and he is walking and I'm runing, this is call the dynamic load.
