In this animated activity, the learner examines how a 74150 IC multiplexer and a 74154 IC demultiplexer work together when their data select lines are connected to the same input devices.

In this learning activity you'll review a visual overview of depth measurement using the depth micrometer.

Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.

Learners reflect on their own attitudes toward change and list them in the order they might experience them. In a separate exercise, they prioritize the actions a group might take when faced with change in the workplace.

In this animated object, learners examine the different types of joints and their movements.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

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

Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.

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.

Review the concepts of safety for Welding

You'll practice calculating the surface area of a frustum of a right circular cone.

You'll practice identifying and explaining safe practices for grinding
