2 Calculation we have already seen use of the scientific calculator and spreadsheet program as tools for the engineering technologist what are some other tools?

3 Measurement - Weight electronic balance scalecan have accuracy of 0.1 g or better multiple units: grams (g) ounces (oz) troy ounce (oz t) 1 oz t ≅ 1.1 oz pennyweight (dwt) 1 dwt = oz t

4 Measurement - Distancevernier/dial caliper – used for precise distance measurements up to approx. 6" can measure inside diameter (ID), outside diameter (OD) or depth

5 Dial Caliper - Componentsdiagram from usage video: https://www.youtube.com/watch?v=_7-6ALptqQQ

6 Measurement - Thicknessmicrometer – used for precise thickness measurements, typically in machining

7 Reading a Micrometer add together major, minor, and thimble unitsAnswer:

8 Computer Tools Internet word processor spreadsheet presentationmathematic apps – MATLAB visualization / rapid dev. - LabVIEW Adobe Acrobat (PDFs)

9 The Internet started as a US DoD-funded project in the 1970snow spans the globe divided into Top-Level Domains (TLDs) based on packet-based protocols and IP addresses TLDs edu US Educational mil US Military gov US Government com US Commercial org Non-profit net Network XX 2-letter Country Code uk = United Kingdom cn = China de = Germany

10 Some Internet Protocolsunderlying protocols Internet Protocol (IP) – packet delivery Transmission Control Protocol (TCP) – reliability user application protocols Telnet – interactive session on remote computer File Transfer Protocol (FTP) – transfers files Simple Mail Transfer Protocol (SMTP) – movement of Network Time Protocol (NTP) – time synchronization Hypertext Transfer Protocol (HTTP) – movement of HTML pages over the world-wide web, created by Tim Berners- Lee 1989† †

12 Word Processor tool to create and edit text advanced features uses:formatting – text/page equations - mathematics tables – data presentation/summary diagrams - illustrations uses: letters, memorandums lab / experiment reports technical reports ex: MS Word, OpenOffice, LibreOffice

13 Spreadsheet tool to track & summarize numeric and other dataoriginated from accounting / finance fields VisiCalc (1978), Lotus (1983) features: row/column grid of cells built-in functions, data manipulation graphing macros ex: MS Excel, OpenOffice, LibreOffice

14 Presentation tool to organize & communicate ideas & facts visuallyvia “slides” views: slide/edit – 1 slide at a time outline – text display sorting – shows all slides in a grid, easy sorting notes – attach text notes/comments to each slide show – for presentation ex: MS PowerPoint, OpenOffice, LibreOffice

15 MATLAB MATLAB (matrix laboratory) is a  multi-paradigm numerical computing environment and fourth-generation programming language. Developed by MathWorks, MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages† MATLAB® is a high-level language and interactive environment for numerical computation, visualization, and programming. Using MATLAB, you can analyze data, develop algorithms, and create models and applications‡ † ‡

16 MATLAB Environment Ex. ∗∗ MATLAB R2011a running on Windows 7

17 LabVIEW (short for Laboratory Virtual Instrument Engineering Workbench) is a system-design platform and development environment for a visual programming language from National Instruments† LabVIEW is a highly productive development environment for creating custom applications that interact with real-world data or signals in fields such as science and engineering‡ A fun, graphical computer development environment with emphasis on data processing and visualization∗ † ‡ ∗ J. Sumey

18 LabVIEW Environment Ex.Front Panel Block Diagram

19 Electronics Tools - 1 digital multimeter (DMM) on-line resources:a highly useful tool for measuring static electrical circuit characteristics voltage, current, resistance, continuity hand-held or benchtop ranges from $6 to $500+ on-line resources: How to Use a DMM Using a DMM

20 Electronics Tools - 2 oscilloscope (scope)a highly useful instrument for viewing time-varying characteristics of circuit signals typically voltage only generally benchtop ranges from $200 to $40k many on-line resources & tutorials!

21 Electronics Tools - 3 (solderless) breadboardNice! (solderless) breadboard a handy tool for quickly prototyping electronic circuits without hard soldered connections many sizes available has particular internal connections $5 - $80 Horrible!

22 Electronics Tools - 4 Ohm’s Lawthe fundamental equation of electric circuits Volts (V) = Current (I) x Resistance (R) volts are measured in volts (V) current measured in Amperes (Amps) resistance measured in Ohms ()
