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.

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.

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.

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.

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 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.

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

In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object. Front, side, and top orthographic views are shown.

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 examine how to convert numbers from rectangular to polar form and from polar to rectangular form using a TI-83 Plus calculator.

Learners examine the relationship of individual parts in an assembly drawing. Assembly drawing notes, fabricated and purchased parts, and sectional views are explained briefly.

Learners examine the correct method for calculating complex reciprocals. The solution for total impedance of a parallel circuit in rectangular form is shown.

This primer introduces the student to the correct method of entering complex numbers in both rectangular and polar form.

Learners read how to create a spreadsheet to determine the voltage drop across a resistor in an AC circuit. The complex functions explained in other learning objects are used in this example.

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

Learners examine the symbols and values that control surface roughness, waviness, and lay. A brief quiz completes the object.
