- 1Chapter 1Material Properties
- 2What are Mechanical propertiesHow objects reply to a force
- 3What is meant by the strength of a materialIt is its ability to withstand an applied force without breaking or permanently bending
- 4Mechanical properties What does this mean? *Properties of the material, including Str, Har, Dur, Dens, Toug,Brit, Mall, Duc-icity, Elasticity
- 5Name 5 types of strengthsBending, compression, sheer, tension, Tortion (explain page 10) give examples
- 6What is durabilityTo resist wear and tear
- 7When is a acryilic not brittleAcryilic is less brittle unless it is heated then it can be moulded
- 8Important Properties when shaping and moulding products are malleability, elasisity, ductability. What does MalleabilityMalleability is where materials can be permanently deformed if hammered rolled or pressed
- 9DuctabilityMaterials ability to be cold deformed by being pulled or pencilled, Heat changes things
- 10Physical Properties1
- 11What are physical propertiesUnaltered by application force or heat this is seen in some plastics
- 12What is fusability-what process is it important inFusability is where something is heated into a liquid and it is used in smelting and fabrication
- 13What does fabrication meanFabrication is the joining together of pieces weather or not they are the same material
- 14What does insulator meanWhere heat is brought into the material and does not pass through, poor conducter ie, plastic cup
- 15Name good electrical conductors and good insulatorsGold, silver, copper/cotten, cermic, wood, plastic
- 16What is a semi-conductor what does it meani.e siliconi.e silicon is usually a poor conductor but on some circumstances it allowes a current to flow
- 17What is mechanical properties and what is physical propertiesRefer to page 10 and 11
