Learners view animations showing how a time-of-flight flowmeter uses ultrasonic sound waves to measure the flow of a liquid.

In this learning activity you'll test your knowledge of the different types of steel rules as well as how to use and read them correctly.

In this interactive object, learners analyze a series-parallel DC circuit problem in a series of steps. Immediate feedback is provided.

Learners read how to determine the location of a contour for a specific location given a TIN.

In this interactive object, learners follow steps to find phase voltages in a partial three-phase power distribution circuit.

The learner examines the four different ways that a caliber can be used to measure dimensions and distances.

Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.

Learners read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.
