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.

In this learning activity you'll analyze line graphs and answer questions about the information shown.

Line Type Identification

Learners read an explanation of line graphs and demonstrate their knowledge of the parts of a graph in an interactive exercise.

In this animated activity, learners read about the types of lines found on blueprints. A quiz completes the activity.

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.

Students use trigonometry to find the coordinates of the blending point where a line and an arc meet. Learners are given the coordinates of the center of the arc, the radius of the arc, and the direction of the line.

In a series of practice problems, learners use the addition or subtraction method to solve systems of linear equations, also called "simultaneous linear equations."

In a series of practice problems, learners use the substitution method to solve systems of linear equations, also called "simultaneous linear equations."

In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.

In manufacturing, controlling the production process is critical. Part of this control is knowing when to make adjustments and when to let the line run. Step onto the production line in our manufacturing plant and learn what process variation is and how it impacts your bottom line.

Students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.

In this animated object, learners study the operation of a linear voltage differential transformer. A brief quiz completes the activity.

In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.

In this animated object, students examine the steps for wiring an electrical circuit from reading a schematic diagram.

Learners examine the proper formats for block letters, modified block letters, simplified letters, memos, e-mail messages, and envelopes.

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 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 learning activity you'll create your own lifeline and realize important events that helped shape who you are today.
