1. 2. (a) For your chosen product:
name two materials/ingredients/components that could be used during manufacture
state two properties of each material/ingredient/component that makes it suitable for use.
No marks will be awarded for repeated answers
 First material/ingredient/component
First material/ingredient/component : Galvanized Steel
Property 1:Hard and tough
Property 2: Does not rust.
Second material/ingredient/component : Aluminium
Property 1: Does not rust
Property 2: Good strength-to-weight ratio, light weight
Third material/ingredient/component : PVC
Property 1: 100% Water resistant
Property 2: Resistant to mildew, solvent, grease and some acids

2. All materials/ingredients/components have some disadvantages in their use.
Select one of the materials/ingredients/components given in your answer to Question 2 (a) and write it below.
  Material/ingredient/component selected:
Steel
Reason: Not environmentally friendly comes from non renewable sources and if not treated will rust (ferrous metal)
Question 2
(a) State two ways in which ICT software can be used during the design of your chosen product.
Modelling ideas using 2D & 3D software
Production of graphics
Question 2
(a) State two ways in which ICT software can be used during the manufacture of your chosen product.
Moulding/cutting wheels using milling machine
Testing of material and structural strength
Cutting vinyl stickers

3. Question 2
(a) State two ways in which you can use ICT to undertake research.
Web ( Existing Products)
Materials (costs, manufacturing methods, new materials)
Questionnaires
(b) (i) State one way in which you can use ICT to present the results of your research.
Tables and Graphs (using Microsoft excel)
(ii) State three reasons why you consider this to be an appropriate method of presentation.
Quick and visual
Easy to compare one thing against another
Range of data can be compared
Results can be sent easily via

4. (b) State what the letters CAD and CAM represent.
Computer Aided Design
Computer Aided Manufacture
(c) State two benefits of using CAD when designing your chosen product.
Easy to alter/modify designs
Can be sent to companies via
Drawings can be sent to manufacturing equipment for manufacturing
Many manufacturers rely on computers in their manufacturing processes.
(d) List three reasons why this has occurred. The reasons must be different from those given in 2 (c) above.
Accuracy (no human error)
Once set up will run indefinitely (round the clock)
After set up costs products will become cheaper

5. Question 2 continued
(e) Explain, giving reasons, why CAM might not be used to make a prototype.
It might be too expensive to produce drawings/moulds etc
Modelling by hand may be needed to see how different parts could fit together
Simple modelling may be required first to allow for more complex designs to be drawn up later
Costs as needles manufacturing processes/mistakes can be avoided
Technology is now extensively used in retail shop outlets.
An example of a product barcode is shown below (Fig. 1).
(f) State two ways the information provided by a barcode can be used by a retailer.
Price
Who made it and when
Stock take
