Learners examine how a linear displacement transducer is used to measure the linear position of a physical object. Animations show the sequential steps of the entire operation.

In this module, you will see the derivation of the total surface area formula for a cylinder and work through several application problems.

Learners examine an animated view of the operation and programming requirements of a PLC Examine-On instruction. A brief quiz completes the activity.

In this learning activity you'll review a visual overview of inside measurement.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

This learning object shows how the shape of a stain defines the angle of impact. In general terms the more circular the stain, the more perpendicular will be the angle at which it struck the surface. The more elliptical the shape of the stain, the more acute the angle will be. With practice and experience, the analyst can recognize the general angle of impact based solely on the shape of the stain.

Learners examine the symbols and values that control surface roughness, waviness, and lay. A brief quiz completes the object.

Students take a quiz to test their knowledge of surface finish.
