In this animated object, learners examine the fundamental operation of a noninverting operational amplifier. A brief quiz completes the activity.

In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.

Students view the development of the transfer function for a RC high pass filter. They also read how a Bode plot is developed through simple approximation techniques for both the magnitude and phase.

In this animated and interactive object, learners calculate the maximum velocity of the work stroke and the return stroke.

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.
