This animated lesson demonstrates hydraulic pressure switch applications when the switch is connected to a ladder circuit to operate in a hydraulic system.

This animated lesson shows several ways that a hydraulic pressure switch, connected in a ladder circuit, causes the cylinder of a hydraulic circuit to perform various applications.

In this animated object, learners examine how to use a programmable logic controller as an alternative to hardwiring a ladder logic circuit.

In this animated lesson, the learner examines how a ladder circuit causes the cylinder of a hydraulic circuit to make a single extension and retraction.

Learners view a horizontal curve and mouse over the diagram to read descriptions of its components and related equations.

Learners study the muscles of the scapula and check their knowledge on each page by identifying the muscles on diagrams and answering a related question about movement.

This interactive object is designed to help learners memorize schematic symbols used in hydraulic diagrams. Learners quiz themselves using electronic flashcards.

Students read about the concepts of saturation and cutoff. They view diagrams that illustrate the interaction of the load line and the family of curves.

Learners mentally manipulate two-dimensional diagrams to visualize the objects in their three-dimensional forms.

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.

This interactive object is designed to help learners memorize schematic symbols used in pneumatic diagrams. Learners quiz themselves using electronic flashcards.

This interactive learning object is designed to help learners memorize the color code used on some hydraulic schematic diagrams. Learners quiz themselves using electronic flashcards.

Learners examine the concept of propagation delay within a TTL logic gate. The concept is explained with the use of timing diagrams and sample calculations.

In this module, we'll be introducing you to SIPOC, a powerful tool that can help you improve your business processes. It's a high-level process mapping tool that helps you identify the key components of a process and how they relate to each other. SIPOC diagrams are often used in Six Sigma and Lean methodologies, but they can be useful for any process improvement initiative. We’ll explain the key SIPOC components and demonstrate how to build one. Then, we’ll walk through a few scenarios and let you build your own.

In this animated object, students view diagrams of the UJT as it is used in the relaxation oscillator circuit. Waveforms illustrate how the circuit operates through several time periods.

Students view diagrams of nails and read the client's nail history. They then determine if the affected nail has a disease or a disorder and recommend salon treatment and home care.

In this screencast, learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.

In this document you'll review drill grinding procedures and web thinning diagrams.

Learners study two diagrams of the lymphatic system and then test their knowledge in drag-and-drop exercises.

In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.
