Learners convert a number from standard form to engineering notation.

Students complete 10 practice problems.

Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.

In this animated object, students observe how the pulsating DC output voltage of a full-wave rectifier is filtered by a capacitor.

In this animated object, learners examine the situation that occurs when any two links of a mechanism lie in the same plane or on a straight line. Crank-sliders and crank-rockers are shown.

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.
