In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.

Learners use this interactive and animated object to examine the use of binary numbers in a programmable logic controller. A brief quiz completes the activity.

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 how the transfer function for a RC high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

Picture of Adira hydraulic shear's operator's panel with part identification and instructions on how to start and stop the shear as well as setting stroke (cutting length).

Introduces two methods of determining bend allowance; one is simple and is an approximate, the other is more precise. Interactive part has learner calculate bend allowance and blank size.

The learner reads about safety considerations for operating a hydraulic metal shear. Text, graphics and a brief assessment are included.

In this learning activity you'll review safety considerations for persons using a hydraulic iron worker and takes a short quiz.

In this learning activity you'll review safety considerations for using hydraulic press brakes.
