In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.

Learners examine the information on a title block and answer questions about that information in an interactive quiz.

In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.

Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.

In this animated and interactive object, learners view American National Standard and International Standard sheet sizes. A quiz completes the activity.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.

In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.

Learners examine pictorial drawings used in engineering including sectioned and exploded drawings. A sketching quiz is provided to help the learner create simple pictorial sketches by using orthographic views and an isometric template.

In this interactive object, learners examine standard and metric thread specifications used in engineering drawings. In a brief quiz, they identify various internal and external thread representations.

The learner will represent very large and very small numbers in engineering notation.

In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.

Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.

In this interactive object, learners answer 25 questions regarding part or assembly drawings. The basic areas of blueprint reading are covered.

Learners examine the complex number function to convert real and imaginary coefficients into a complex number.

In this interactive object, students view an animated depiction of Class 3 levers. A matching quiz completes the activity.

Students follow the correct keystrokes to calculate the logarithm of a number.

In this animated learning object, users view the process of entering a formula in an Excel spreadsheet. Several different methods and associated examples are given.

Learners examine the use of the reciprocal key on the TI-83 Plus calculator to determine parallel resistance.

In this interactive object, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information. A brief quiz completes the activity.
