In this screencast, learners follow steps to determine the proper starting belt length for a timing, flat, or v-belt drive.

Students view a video that shows the correct methods for starting a GTAW weld pool and adding filler. It focuses on the two problems that many students have – adding filler too soon and angling the torch so that the filler melts prematurely on the filler rod. Note: This activity is 3.6 mb.

Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.

The learner will understand the importance of following instructions.

This activity is a simulation that allows the learner to practice personal protective equipment tasks.

This activity is a simulation that allows the learner to practice personal protective equipment tasks.

In this simulation activity, an electrician will troubleshoot an AC motor that is overheating. Before accessing blueprints and then using a multimeter to find the fault, the learner will follow safety protocols by following lock-out tag-out procedures and then suit up with appropriate (PPE) personal protection equipment.

In this simulation activity, an electrician troubleshoots a defective compressor motor that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.
