In this animated and interactive object, learners calculate the maximum velocity of the work stroke and the return stroke.

Walk through the subscriber loop and learn how the signal travels from the central office to the subscriber.

The current-to-voltage conversion of the transresistance amplifier is examined. The formulas for output voltage and impedance are defined and an example ties the concepts together.

Learners examine the elements of a data file memory of an Allen-Bradley SLC-500 programmable controller. A quiz completes the activity.

Learners answer questions about internal combustion engines using a game board format. This learning object can be used individually, in small groups, or as a class activity to provide an alternative self-assessment tool.

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 interactive object, learners demonstrate the proper tightening sequence for mechanically joining two mating surfaces.

In this animated object, learners examine the operation of an optocoupler, specifically how it is connected to external components to provide interfacing and isolation and how it responds to excessive frequencies. A quiz completes the activity.

Learners read a description of the function of the coupling switch on an oscilloscope and how its setting affects measurements of DC, AC, and combined voltages. A brief quiz completes the activity.

You'll practice identifying the major components of an engine lathe.
