In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
The Elementary AC Generator
By Terry Bartelt
Learners view animations showing the operation of the internal parts of an AC generator. A short quiz completes the activity.
Learners view an animation showing how the volume of a given quantity of gas varies directly with its temperature.
Sequencer Output Instruction for the SLC-500 PLC
By Craig Hemken
Learners examine the fundamental concepts of sequencer output instruction. A simulated example shows a sequencer in operation.
Pressure Measurement Scales
Learners compare the three scales used in pressure measurements: gage, absolute, and vacuum. A brief quiz completes the activity.
Identifying Lever Classes
By James Bourassa
In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.
RPM of AC Motors
Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.
The DC Shunt Motor
Learners examine the operation of a DC Shunt motor and its characteristics. A quiz completes the activity.
In this animated activity, learners examine how the speed of a motor may change if the voltage from the power source fluctuates due to power line irregularities. This lesson has audio content.
Basic DC Electrical Motor Construction
Learners examine the internal parts of a DC electrical motor and then text their knowledge in a drag-and-drop exercise.
