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 will write effective business messages that incorporate a second-person point of view and focus on the benefit to the reader. This approach is often used to create positive messages, neutral messages, and inquiry messages in business settings.

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 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, 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 object, learners practice their 3D visualization skills by identifying the correct isometric view of an object.

Students view a world map and click on a country or continent to read about how the people there view time. A brief quiz concludes the activity.

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 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 test their ability to visualize a three-step block in this interactive exercise that features animated pictorial views.

The learner will understand how to view an object for interpretation in the standard orthographic format and then accurately sketch three orthographic views using 3rd angle projection.

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 answer 25 questions regarding part or assembly drawings. The basic areas of blueprint reading are covered.

Learners view animations showing how hubs and switches work in local area network configurations.

In this animated object, learners examine the mechanical configuration of a three-way switch and how it operates in a circuit. They also view diagrams showing the use of an ohmmeter to determine the electrical connections.

Learners view a sample of the keystrokes from a TI-35X or 36X calculator that are required to solve for the instantaneous voltage of a charging RC circuit.

Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.

Learners view an animated explanation of why an adjustment of the output voltage by an AC drive is required to maintain a constant torque as the frequency is varied.

Students view the mathematical expression of an AC waveform with respect to time (t) and read about the different components of this expression.

Learners view an animation showing the operation of a Vortex flowmeter that is used to measure flow in a process control system.
