EAT100 – DESIGN, DRAWING AND PRACTICAL SKILLS
REFERRED/DEFERRED ASSIGNMENT
PLEASE NOTE: THIS IS AN INDIVIVDUAL ASSIGNMENT NOT A GROUP
ASSIGNMENT
Please read the following text carefully
Drawing on your experiences during and your involvement in the Electric Cart group
project, answer ALL of the following questions:
1. DFMEA was used as a tool during your groups design process.
Describe:
a. what is meant by the term DFMEA
b. How a Design Specification document can inform the contents of the
DFMEA analysis.
Using three example functions of a design demonstrate how these might be
analysed with DFMEA and suggest outcomes of the study. (25 Marks)
2. When working as part of a multi-disciplinary design team the project manager
often uses a Gantt chart to plan, monitor and control the project.
List five considerations a project manager must take into account when creating
a Gantt chart explaining the reasons for their importance to successful delivery of
a project. (25 Marks)
3. For a successfully designed electrically powered cart such as those created
during the sessional design project, energy stored in batteries is converted into
motion. Unfortunately no energy transfer system is 100% efficient. List five loses
identified in such a system and describe how significant these losses are likely to
be and how the loses may be reduced. (25 Marks)
4. Assuming you built the electrically powered cart described in question 3, describe
a suitable testing strategy which could be used to optimise its speed, efficiency
and payload carrying capability. You should describe the measurements you take
and how you will use them as well as the equipment needed to take them.
