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 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.

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.

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.

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.

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.

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

Learners examine how to raise a number to a power using the TI-83 Plus calculator. Sample problems are given using both real and complex numbers.

In this interactive object, learners are given the RPM, the pulley diameter, and the force, and proceed to calculate belt velocity and horsepower.

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

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

Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units.

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

Learners develop 3D visualization skills by examining front, side, and top orthographic views of objects. Using this information, students select the corresponding isometric view of each object.

In this interactive object, students view an animated depiction of Class 1 levers. A matching quiz completes the activity.

Students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.
