This interactive activity represents the grid modeling technique, a heuristic model for choosing a centralized location for a manufacturing or distribution center within a supply chain network. The formula calculates a central point between the suppliers and the markets. This object requires the latest version of Flash Player.

This learning object allows the learner to view a video demonstration of a forklift truck inspection.

In this interactive object, learners vary the value of the resistance to see how it affects current. Example problems are included.

In this animated activity, learners examine how residual magnetism causes magnetic hysteresis.

Students view the layout and operation of a digital logic probe.

In this animated object, learners examine how various types of positive and non-positive displacement hydraulic pumps work.

Learners examine how fluid enters the inlet of a hydraulic pump because of atmospheric pressure and how pressure is created at the pump’s outlet. This object includes audio.

In this animated object, learners study the problems that develop if the scan time of a PLC is too slow.

Students read the terms associated with the Bipolar Junction Transistor (BJT) . They also view formulas for dc current and voltage.

The explanation and use of timing diagrams used in digital electronics to graphically show the operation of various circuits are given.

In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.
