- 1Define FunctionThe use or purpose of a structure.
- 2List some examples of functions of a structure.*Transporting
*Sheltering
*Protecting
*Lifting
*Containing - 3What is a structure?Any object that provides support.
- 4What is the difference between a static load and a dynamic load?Statics loads do not move.
Dynamic Loads DO move. - 5Give an Example of a static load.A TV on a TV stand.
- 6Give an Example of a dynamic load.A car on a bridge.
- 7What does "aesthetics" of a structure refer to?The pleasing appearance of it.
- 8Define Force.Something that Jedi use to throw their enemy and gain advantage of the fight.
(jk... A push or pull that tends to cause an object to change its movement or shape. - 9What is an external force?The force applied to a structure from something else.
- 10what is an internal force?The forces acting within structures.
- 11List 3 forces that may act within a structure.1. Compression- when parts of a structure press or push against each other
2. Tension- when parts of a structure pull away or apart from each other
3. Sheer- when parts of a structure move in opposite directions of each other. - 12Define frictionThe resistance or drag you encounter when you drag an object across the floor.
- 13Define flexibility.The ability of a material to be bent under force without breaking, like a tree in the wind.
- 14Define deformation.The change of the shape in a structure or any structural component, because the material is unable to resist the load acting on it.
- 15What is the difference between flexibility and deformation?Deformation changes the shape because it cant resist the force. Flexibility is the ability to bend and not break.
- 16What are the 2 different ways that structural components can be joined?1.Friction
2.Bonding - 17What materials could you use to join structural components?Friction- nails, screws, staples, interlocking pieces, mass
Bonding- glue, cement, tape, welds - 18****** What are performance requirements?******Conditions that a structure must meet after it is built.
(A triangle is the strongest structural shape) - 19****** List 2 performance requirements that there could be for a bridge.******1. It must be able to hold a certain number of cars and people.
2. It must resist wind gusts up to 200 km/hr. - 20The effect of a force on a structure depends on 3 things.1. The magnitude, or size of the force.
2. The direction of the force.
3. The location of the force.
