What you will do in ME 2110
• Design and evaluate devices.Design and evaluate devices.
• Document these designs using drawings• Document these designs using drawings.– Drawings should be computer-prepared– All design illustrations should represent your workg p y
• Characterize and evaluate the designs in written reports. g p

Technical Communication—IFiFigures
• Drawings display designs• Flowcharts display sequences of events• Tables display data
G h h i• Graphs show comparisons• Matrices display decision criteria
S ifi ti Sh t di l l ti it i• Specification Sheets display evaluation criteria

Technical Communication—IIDescribing FiguresDescribing Figures
• What is shown?• What is important in the figure or table?What is important in the figure or table?• What does this system do?
Wh d hi i h l d ?• What does this matrix help you to do?
6J. Donnell / ME 2110, 2010
Reports present accomplishments
Accomplishments are tangible:
• A device (shown in a drawing)
• A plan for solving a problemA plan for solving a problem(shown in flowcharts and tables)

Reports do not present d i i t tiadministration
• Team meetingsg
• Brainstorming sessionsg
• Concepts that were discussed but not drawnConcepts that were discussed but not drawn
8J. Donnell / ME 2110, 2010
Reports require teamwork
Team members must take charge of:
• Text• Drawing• QualityQuality
– Coordinate figure numbers with citations– Proofread the documentProofread the document– Verify that page design is appropriate– Verify that the document is complete

Oral Presentations in ME 2110
• State your name and your teammates’ namesS h j bj i d h h ll (• State the project objective and the challenge (as available)D ib d i ( th li h t )• Describe your design (or other accomplishments)– Display design drawings (or other charts)
l l• Evaluate your results – What worked
Wh t f il d– What failed– What you would do differently
• Summarize points and ask for questions16
• Summarize points and ask for questionsJ. Donnell / ME 2110, 2010
Displaying Illustrations
• Make your own drawingsIf an illustration is not original, you will be in trouble
• Label the drawings• Number the figures • Provide captions• Cite and describe figures:g
“Figure 3 shows…..”
