Troubleshooting a Three Phase Motor that is Overheating
By Excelsior College
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.
Quick-Return Mechanism Velocity Calculations
By James Bourassa, John Rosz
In this animated and interactive object, learners calculate the maximum velocity of the work stroke and the return stroke.
Mechanical Advantage (Screencast)
Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.
Using Blueprints to Troubleshoot a Defective Water Pump
In this simulation activity, an electrician troubleshoots a defective water pump 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.
Using Blueprints to Troubleshoot a Defective Compressor Motor
