Learners examine the concept of the RC time constant. The instantaneous voltage across the capacitor is calculated.

Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.

Learners read an explanation of the RL time constant and examine the formula for calculating the instantaneous current value. The current is graphed as it climbs to maximum or drops to zero. Note* In the formulas in this module, the Greek letter epsilon should be the mathematical constant 'e'.

Students read an introduction to the electronic workbench and view a demonstration of how to open a file for circuit simulation.

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.
