Learners study how a circuit converts the AC output of a linear voltage differential transformer (LVDT) into variable DC voltage. It is recommended that learners view the learning object IAU7807, “The LVDT: A Linear Voltage Differential Transformer in Action” before going through this object.

In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

In this interactive object, learners read how to determine the force created by a hydraulic cylinder during extension and retraction. A brief quiz completes the activity.

In this animated object, learners examine the switch settings for the on-delay, off-delay, and one-shot timing functions of an optical sensor. A brief quiz completes the activity.

In this animated object, learners examine the properties of the peptide bond and how the bond relates to the structure of hair.

Learners follow the steps required to perform the Ziegler-Nichols reaction curve process identification procedure.

Learners study the mathematical calculations used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Reaction Curve.

In this animated lesson, learners read about the disulfide bond, the second strongest chemical bond in the hair. This bond can only be altered by chemicals.

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.
