Newton's Laws of Motion
How many laws did Newton theorize?
What is 3
The definition of aerodynamic
What is the study of how air moves things around
How many forces affect the principles of flight?
4
What is a structure?
An object or system built to serve a specific purpose
Do static loads change over time?
No - Static loads remain consistent
Roughly when did Newton propose the 3 laws of motion?
What is during the 1600's
Define altitude
What is a measure of the height of an object above ground level
What is weight?
What is is the force that pulls everything toward the Earth due to gravity?
Why are triangles often used?
It distributes force evenly
What is a shell structure?
Uses an outside layer to provide support
A body that continues to be at rest or in motion unless an external force is applied to it is what law?
What is the first law of motion
What is mass? No, not church....
What is a measure of how much matter is in something
Is compression an internal or external force? What is compression?
External - Pushes things together
What comes first? Form or function?
Function - The shape (form) of a structure is based on its purpose (function)
What is a static load?
A static load is a load which has a force that stays the same.
What is the 3rd Law of Motion according to Newton?
What is for every action, there is an equal and opposite reaction.
The most aerodynamic shape
What is a teardrop
What is torsion?
Torsion is twisting of an object
Name 2 important factors when designing a building
- weight load
-aesthetics
-function
The weight of a roof is a static load, true or false?
True
What law explains a bowling ball needing more force than a baseball to knock down 10 bowling pins?
What is Newton's second law of motion
How is air affected by altitude? 2 factual points needed!
The air pressure decreases the higher you are
Pressure decreases at high altitudes because there is less force pushing downward
Is tension in a bridge cable an internal or external force?
Internal
Why would a bridge be shaped like an arch?
To spread weight evenly
People walking over a bridge is an example of what type of load
What is dynamic load
