Learners examine the different types of lines used on a P&ID diagram and the types of connections they represent. They test their knowledge in a matching exercise.
Learners view a demonstration showing that line-neutral voltages and line-line voltages are not in-phase with each other, but have a definite 30-degree relationship.
Learners read an explanation of line graphs and demonstrate their knowledge of the parts of a graph in an interactive exercise.
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 learning activity you'll analyze line graphs and answer questions about the information shown.
In this animated activity, learners read about the types of lines found on blueprints. A quiz completes the activity.
In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.
In this animated object, learners study the operation of a linear voltage differential transformer. A brief quiz completes the activity.
In this animated object, students examine the steps for wiring an electrical circuit from reading a schematic diagram.
In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.
In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.
In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.
Using a memory shortcut for calculations, the learner determines line and phase values of current in a three-phase AC configuration. Practice problems complete the activity.
Students read about the concepts of saturation and cutoff. They view diagrams that illustrate the interaction of the load line and the family of curves.
In this animated activity, learners examine how the speed of a motor may change if the voltage from the power source fluctuates due to power line irregularities. This lesson has audio content.
Students read how the transfer function is developed for an RC low-pass filter. A straight line Bode plot is drawn through close approximations.
In this screencast you'll generate your own speech outline from the information provided.

Learners examine how a force may be considered to act at any point along its line of action as long as the magnitude and direction of the force remain unchanged. Numerical verification is provided.
In this screencast, you'll examine writing a sentence outline using complete sentences for headings, subheadings, main points, and subpoints.
In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.
