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.

Learners read how to create a spreadsheet to determine the voltage drop across a resistor in an AC circuit. The complex functions explained in other learning objects are used in this example.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.

The learner calculates the resultant of multiple forces acting in a concurrent, coplanar load condition.

In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A quiz completes the activity.

In this interactive object, learners calculate a centroid of a composite area by first creating a chart. A short quiz completes the activity.

In this animated and interactive object, learners calculate the area and centroid of a rectangle.

In this animated and interactive object, learners calculate the area and centroid of a triangle.

In this animated and interactive object, learners calculate the area and centroid of a circle.
