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.

This project gives a drawing with steps to complete the activity.

This document is a visual and text description of using tapers with a taper attachment on a lathe.

This project gives a drawing with steps to complete the activity.

In this animated object, students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.

In this animated object, learners examine the situation that occurs when any two links of a mechanism lie in the same plane or on a straight line. Crank-sliders and crank-rockers are shown.

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 examine problem areas related to patients with arthritic conditions. They also identify treatment precautions and design a treatment plan.

In this interactive object, the learner reads an explanation of how various shielding gases are used in GMAW and FCAW. An exercise completes the activity.
