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

In this animated and interactive object, learners view American National Standard and International Standard sheet sizes. 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.

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 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.

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.

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.

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

The learner examines the setup process of a TI-83 Plus calculator. The process is demonstrated and examples are given.

Learners read how to set up a TI-86 calculator. The process is demonstrated and examples are given.

Learners solve word problems involving basic mechanical principles such as torque, horsepower, work, and power. Students who have problems with a particular word problem may try it again with a different set of numbers.

In this learning activity you'll practice converting between degree minute second and decimal degree.

Learners read how to raise a number to a power using the TI-86 calculator. Examples are given for both real and complex numbers.

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