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

Learners examine the operation of an inductive proximity sensor in this animated object. A brief quiz completes the activity.

Learners study the effect of reflected and transmitted energy on the measurement of emitted energy by a non-blackbody. A short quiz completes the activity.

Learners study the theory of operation for a ratio pyrometer that measures temperature. A short quiz completes the activity.

In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
