Engineering - Exam Papers - HL - Project - 2008
Materials handling technology, for transporting building material between locations and levels on a building site, in an integral part of modern construction environment.
Design a model of a portable materials handling device to the
general specifications outlined below.
The machine should:
- Be capable of delivering materials to and from different levels;
- Be mobile to facilitate transportation between site locations;
- Be controlled by an ON/OFF switch;
- Include an electronic indicator to signal that the device is in operation.
Presentation of the completed machine should ensure
- All main operating features are clearly visible
- The longest dimension of the model does not
- Electric power does not exceed 9 volts.
- Design Process (40 marks)
A design folio must be compiled which will detail
- Analysis of the given brief and investigation of
- Criteria for selection of your own individual
solution and production drawings/plans;
- Testing and evaluation of your design solution;
- Special instructions, if required, regarding the
testing of solution by examiner.
Note: Computer-aided design (CAD) should be
used where possible.
- Design Realisation (110 marks)
Using appropriate materials, make the machine
according to your own individual design plans.
Computer numerical control (CNC) technology should
be used, where possible, to support manufacture. You
are required to manufacture and assemble all the
parts, subject to the following guidelines:
- Standard components may be used to support the.
assembly and interconnection of various pans;
- Unnecessary recycling will result in lost marks. Re-cycling will be acceptable only in cases
where a complex part cannot readily be made in the school.
- Bought-in electronic solutions will result in
- Adhesives, if used, should be applied sparingly.
- Project presentation
Your completed project consisting of the device and
design folio, both clearly identified with your
examination number, must be available to the
Marks are awarded for quality of presentation and
finished appearance of both the device and folio.
