In this animated object, learners examine the operation of two-way, three-way, and four-way directional control valves used in pneumatic systems.

In this animated object, learners examine the fundamental operation of a noninverting operational amplifier. A brief quiz completes the activity.

In this animated activity, learners examine the circuitry in a DC variable speed drive that keeps the motor running at a constant speed as the load varies.

Students are provided with a Monthly Expenses Worksheet to help them understand the basics of budgeting, income, and spending.

Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.

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

Learners examine the sourcing and sinking of conventional current at a PLC output module and the type of field device to which it is connected. This interactive learning object includes six quiz questions.

Users read work instructions and view a drawing and calculations for turning on a lathe using a digital readout.

In this interactive object, learners read about the occupations that are most at risk for bloodborne pathogen exposure. They also read about the most common pathogens and how they are transmitted. This learning object is based on information from the U.S. Occupational Safety and Health Administration.

Learners read how the transfer function for a RC high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

Students read how the transfer function is developed for an RC low-pass filter. A straight line Bode plot is drawn through close approximations.

In this animated activity, students view the operation of a 4-bit serial-in serial-out register. A brief quiz completes the learning object.

Learners examine the labeling scheme used in ladder logic diagrams to identify components, wires, rungs, and rails. This activity includes self-check questions.

This learning object offers a brief summary of the impact of nanotechnology on automobile tires. Learners look at the future of cars, especially the safety and future of automobile tires.

Explore how to combine Waterfall and Agile methodologies for your next software development project.

In a series of three interactive exercises, learners explore the relationship between process cycle time and defect detection, and between process cyle time and smaller batch sizes. The techniques of lean/JIT are applied to achieve the continuous improvement (kaizen) goal of reducing inventory by pursuing one-piece flow.

Learners practice reading prints of a hub. They identify information located on the print and calculate missing dimensions.

In this learning activity, you’ll explore the Data Definition Language (DDL) including its three main commands: CREATE, ALTER, and DROP.

In this quiz you'll identify common hand tools by their function.

In this interactive activity, learners insert the router terms that each acronym stands for. Each of the acronyms is formed from the key letters in a term that relates to routers.

Learners read and listen to the pronunciation of hundreds of medical terms that are arranged in a "jukebox." The terms are listed alphabetically and according to the following categories: aerobic and anaerobic microorganisms, blood bank, coagulation, fungi microorganisms, hematology, protozoa, and urinalysis. This learning activity requires a computer that is equipped with speakers.

In this interactive object, learners use the Pythagorean Theorem to calculate forces.

Learners read an analogy comparing an electrical transformer to mechanical gears.
