• Word - Inserting Objects
• Word, like most full-featured Windows programs,
  supports Object Linking and Embedding (OLE).
  This allows objects created with other programs
  to be inserted (or embedded) into Word. Later
  in the course we will look at embedding Excel
  spreadsheets or graphs into Word and into
  PowerPoint. For now we will focus on embedding
  Microsoft Equation objects into Word. We will
  also look at using the Drawing Tools available in
  Microsoft Office applications.
• To insert an Equation, select Insert - Object -
  Microsoft Equation 3.0.

Problems? What if Microsoft Equation isnt
installed? Many people install Microsoft Office
using a Typical Installation which may omit the
Equation Editor. If this is the case on your
computer, when you select the Equation Editor you
may be prompted to insert the original CD to
install the new feature.

• Word - Inserting a Microsoft Equation object
• Select Insert Object Microsoft Equation 3.0
• Note that a work area appears, a toolbar appears,
  and the main menu changes.
• Clicking outside the work area saves the work and
  returns to Word.
• Double-clicking on the inserted object will
  re-launch the equation editor.

• Selecting the button shown on the toolbar below
  opens another toolbar which contains a
  numerator/denominator tool, a square root tool,
  etc.
• To generate the equation below
• type x
• pick numerator/denominator tool,
• type AB
• use mouse to click denominator
• type C
• pick square root tool
• pick numerator/denominator tool
• type D,
• move mouse to denominator
• type E

Using the Placeholder Using the right arrow to
make the placeholder (cursor) grow until it
covers the entire equation and then pressing
Enter will cause the editor to go to a new line
(or you could insert another equation box). Use
the integral tool shown to create an integral.
The integral equation below is completed using
the Greek letter tool for the symbol for alpha
and the toolbar to its left for the infinity
symbol.

Adding spaces Use Style - Text The equation
editor automatically works in math style which
does not allow for spaces. If you need spaces in
an equation, pick Style Text from the main
menu (see below). Text style will allow spaces
to be typed and the editor will automatically
switch back to math style when it encounters a
math symbol. To put bars over the variables A,
B, and C below, highlight each one and then pick
the text tool that shows a dotted box with a line
over it. Note the spaces between A and .

Resizing an Equation To change the size of an
equation, click outside of the equation box to
return to Word (or Excel, etc.) and resize the
equation box as you might resize a picture.
7
Lecture 9 EGR 120 Introduction to
Engineering

• Moving an Equation to any place on the page
• Objects, including equation boxes and pictures,
  are typically line-oriented by default.
• To make an object free floating so that you can
  place it anywhere on a page
• Right-click on the object
• Select Format Object
• Select Layout
• Change the layout from
• In line with text to Tight
• You can now move the object
• anywhere on the page with
• the mouse.

• Drawing Tools in Microsoft Office
• For more complex drawings we might use AutoCAD,
  Inventor, etc., but Microsoft Office contains
  drawing tools that are convenient and easy to use
  for simple drawings.
• Pick Insert Shapes to see the menu of drawing
  tools shown below.

Used to draw text boxes (right-click On box to
change the fill and/or border)

Lecture 9 EGR 120 Introduction to
Engineering

• Getting Started try a few simple drawing tools

10
Lecture 9 EGR 120 Introduction to
Engineering

• Example Draw a rectangle. It may be filled
  with a color like the green box below. Change
  the box to
• No Fill
• Red Outline
• 1.5 Point (Weight)

Changing the color (Shape Fill), line type (Shape
Outline) and line width (Weight) Note that
Office 2007 uses context sensitive ribbons
(menus), so after drawing a rectangle, the ribbon
should change to show useful options for editing
the rectangle. If the ribbon indicated below
does not appear, double-click on the rectangle.

• Arcs
• Select the Arc tool (under Basic Shapes) from the
  Shapes menu and draw an arc.
• Remove the Shape Fill
• Copy the arc and then rotate the copied arc
  (select Rotate (then Rotate Right 90 degrees)
  from the Format menu)
• Move the arcs, add lines, and add a circle to
  create the following object

12
Lecture 9 EGR 120 Introduction to
Engineering

• Grouping
• Several objects (lines, arcs, etc) can be grouped
  to form one larger object.
• The larger object can then be resized, rotated,
  etc.
• To group objects
• Highlight all of the objects to be grouped with
  the mouse.
• Select Group from the Format ribbon.

• Note that objects can be similarly ungrouped in
  order to edit individual parts.

13
Lecture 9 EGR 120 Introduction to
Engineering

• Grouping - Example
• Group the objects from the previous pages
• Copy several versions of the grouped object.
• Resize some of the grouped objects.
• Rotate some of the grouped objects.

Lecture 9 EGR 120 Introduction to
Engineering

• Grids - The drawing tools include some useful
  grid settings
• Snap Objects to Grid - This is like drawing on a
  sheet of graph paper where lines and other
  features can only be anchored to intersections of
  the graph paper.
• Snap Objects to Other Objects The end of one
  object (such as a line) will automatically try to
  connect to the end of another object.
• To change grid options, select Align Grid
  Settings from the Format ribbon.

15
Lecture 9 EGR 120 Introduction to
Engineering

• Grids - Sometimes it can be useful to turn off
  grid snap features in order to control precise
  placement of objects.
• Example
• Draw the triangle below using 3 lines.
• Select Snap Objects to other Objects to be sure
  that the lines are exactly joined at the
  vertices.
• Turn off the grid snap features.
• Add a text box with the angle (use Insert
  Symbol for the degree mark)
• Remove any fill or border from the angle box.
• Add an arc to indicate the angle being measured.
• Change the ends of the arc to arrowheads (right
  click on arc and select format shape line style
  arrow settings).
• Adjust the arc so that it just touches the
• triangle (hard to do if the grid snap is on)
• Group all objects

• Word - Creating Greek Letters and Special Symbols
• There are 2 methods for creating Greek letters
  and special symbols in Word.
• 1) Select Insert - Symbol from the main menu.
  The toolbar of special symbols that appears is
  shown below. Note that it uses the Symbol font.

2) Change any text, anywhere to the Symbol font.
This is useful in applications that do not have
an Insert Symbol command. Refer to the table
to the right and type the English letter
corresponding the desired Greek letter. Then
highlight the English letter and change the font
(right-click in the highlighted area and select
FONT) to Symbol font. For example, type angle b
30 degrees, highlight the letter b, and change
its font to the Symbol font so that Greek letter
b will appear resulting in angle b 30 degrees.
Try it! Use both methods to type the following
trig identity cos(a b) cos(a)cos(b)
sin(a)sin(b)

Formal problem solutions Microsoft Equation and
the Microsoft Drawing Tools are very useful when
generating engineering documents on the computer.
Examples might include lab reports, team
reports, homework problems, PowerPoint
presentations, etc. The formal solution to an
engineering problem is shown on the following
page.

FIND section. State exactly what quantities are
to be determined.
FIND Determine the length of AB.
SOLUTION Using the law of cosines, angle DCE
can be determined as follows (DE)2 (CD)2
(CE)2 - 2(CD)(CE)cos(DCE) (40)2 (80)2 (100)2
- 2(80)(100)cos(DCE) cos(DCE) 0.925 DCE
cos-1(0.925) 22.33o and by inspection it is
clear that angle DCE angle ACB Now use the law
of cosines on triangle ABC to find AB (AB)2
(AC)2 (BC)2 - 2(AC)(BC)cos(ACB) (AB)2 (400)2
(450)2 - 2(400)(450)cos(22.33o) (AB)2 29500
