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 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.

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 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.

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 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.

Learners examine the use of the tolerances displayed in a title block by calculating the minimum and maximum allowable size of a fabricated part. In a brief quiz, students determine whether a part is usable or should be scrapped.

Learners follow step-by-step instructions for calculating the square root of a number using the TI-83 Plus scientific calculator. Steps for determining impedance are also shown.

This primer introduces the student to the proper use of the "EE" function to perform calculations on very large or very small numbers.

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

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

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

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 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.
