In this animated and interactive object, learners study the synchronous rotational speed of the magnetic field created by the stator of an AC Motor.

In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.

In this learning activity you'll follow the process of converting digital data into a series of analog signals.

Students read an explanation of the operation of an operational amplifier that functions as a comparator.

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 activity, learners examine how cavitation occurs in a hydraulic pump. A video clip is included. Learners then test their knowledge in a brief quiz.

In this animated object, learners examine how aeration develops in a hydraulic pump. A brief quiz completes the activity.

Learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.

In this interactive object, learners examine how hydraulic oil is contaminated, the types of damage contamination can cause, and the methods used to clean the oil.
