Engineering

• What is a planned procedure

  Planned procedures are detailed instructions to guide you through a practical task
• Planned procedure step by step

  1. Read through the whole procedure
  2. Collect materials and components
  3. Collect and assemble the equipment
  4. Follow procedure steps
  5. Ensure you have completed all the elements if the procedure
• What is a prototype?

  A prototype is the first working version of a new product. Testing a prototype allows any problems to be solved before a product is put into production or sold.
• What is a model?

  Sometimes products are to large to build prototypes. Instead use a scaled down model to test the product.
• What is non-destructive testing 


  Taking measurements to find out how the product behaves in different situations (force, length, velocity, voltage)
• What is destructive testing?

  Sometimes the product needs needs to be able to behave in extreme situations. These tests can only be done once.
• Reverse engineering 


  Carefully disassembling and analysing a product
• Disassembly 


  Taking apart
• Assemble 


  Putting together carefully using instructions
• Ferrous metals

  • Contain Iron
  • Includes mild steel, high carbon steel and stainless steel
  • E.g., nuts, bolts and structural components
• Non-ferrous metal

  • Don't contain iron
  • Includes copper, aluminium and brass
  • E.g., lightweight structures, electrical conductors
• Ceramics

  • Include glass, pottery and bricks
  • E.g., windows, pottery and bricks for buildings
• Thermosetting polymers

  • Once thermosetting polymers are formed there shape is permanent
  • E.g., electrical fitting
• Thermoforming polymers

  • Including nylon, ABS, PET and PVC
  • E.g.,water bottles and car steering wheels
