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.

Phase Relationships Between Line-Neutral and Line-Line Voltages

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 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.

Finding the Coordinates of the Point Where an Arc Blends Into a Line

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.

Solving Systems of Linear Equations Using the Addition or Subtraction Method (Screencast)

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

Solving Systems of Linear Equations Using the Substitution Method

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

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.

Basic Elements of Dimensions Used in Engineering Drawings

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.
