Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.

In this animated object, learners examine the two types of optical encoders used in automation applications: incremental and absolute. A brief quiz completes the activity.

Learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.

Students view photos of an electric pencil sharpener as it is disassembled. The learning object is intended to prepare students to be able to identify the components and create an assembly process in a future activity.

In this animated activity, learners read about air loss in a pneumatic system and ways to reduce the leakage. The object includes audio.

In this animated object, learners examine the operation of two-way, three-way, and four-way directional control valves used in pneumatic systems.

Learners use animated needle valves and check valves to change the speed of a pneumatic cylinder as it extends and retracts. A brief quiz completes the learning object.

In this animated object, learners examine the operation of a pneumatic directional control valve using air pilot lines.

This animated lesson shows how pushing a start or stop button on a ladder circuit causes the cylinder of a hydraulic circuit to extend and retract.
