Structures and Force
| Question | Answer |
|---|---|
| What are the three types of structures? | Shell, Frame and Mass |
| What are there categories? | Natural and Manufactured |
| What is a rigid joint? | A joint that allows doesn't allow movement |
| What is a mobile joint? | a joint that does allow movement |
| What does function mean? | It is the main purpose of the structure. |
| What are some examples of a function? | Supporting, containing or sheltering |
| What are aesthetics? | the study of beauty in nature. If the structure looks nice, it is aesthetically pleasing |
| What is a margin of safety? | a standard set for how much a structure can hold. It is usually a set weight that is over the usual standard |
| What are material? | What a structure is made of. |
| What are composite material? | materials that incorporate other materials to make a certain specification. Such as reinforced concrete. |
| How do you stabilize a structure? | You find the centre of gravity and have a good foundation. Speed also helps to stabilize. |
| What is a dead load and what is a live load? | A dead load is a load that is fixated on the structure and can't be moved. It is permanent. A live load is a load that can be removed at any time. |
| What is a tension and shear force? | A tension force is the act of a structure being pulled apart and both ends. A shear force is the act of 2 parts of a structure that slide past each other in opposite directions |
| What is a compression and torsion force? | A compression force is the act of a structure being squished down. A torsion force is the act of a structure being twisted on each side in opposite directions. |
| How can structures be joined? | They can be joined with fasteners, interlocking shapes, ties, adhesives and melting |
| What is the difference between mass and weight? | mass measures how much something is made of. Weight is the amount of gravity excerted on an object. |
| What is weight and mass measured in | Weight is measured in Newtons and Mass is measured in Grams and Kilograms. |
| What is the difference between compressive and tensile strength? | Compressive strength is the strength to withstand being pushed together, and tensile strength is the strength to withstand being pulled apart. |
| What is spin stabilization? | It explains that an object that isn't mounted on a solid surface for stability can be stable if it is spinning rapidly. |
| Why is it important to have a stable foundation? | because the structure needs support that will keep it mounted solidly other wise it will start to tip over due to compression. |
| What is friction? | The resistant force. |
