(a) List four additional points about the function of such a device that you consider to be important. [4 (b) Use sketches and notes to show two different methods by which a device of this type could move. [4 (c) Develop and sketch ideas for the device. [12 (d) Evaluate your ideas and justify why you have chosen one idea to develop more fully. [8 (e) Draw, using a method of your own choice, a full solution to the problem. Include construction details and major dimensions. (12: (f) Suggest suitable specific materials for your solution and give reasons for your choice. [4 (g) Outline a method used to manufacture one part of your solution in the school workshop. [6 @©UCLES 2010 0445/13/O/N/10
