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.
