In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
Orthographic Projection #1
By Glenn Sokolowski
In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.
By Terry Bartelt
Learners examine how an electromagnet is formed. Animated illustrations show current running through a coil wrapped around an iron core.
Interpreting Engineering Drawings: Title and Revision Blocks
Learners examine the information on a title block and answer questions about that information in an interactive quiz.
Analog Voltmeter Operation
Students follow the procedure to measure voltage with an analog voltmeter. They examine the use of the Function Switch and the Range Switch. A brief quiz completes the activity.
AC Current Flow
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.
Students read about the concept of true power and view examples of how it is dissipated as heat is provided.
Learners read an explanation of the concept of apparent power in a power distribution system involving motors, generators, and transformers. A quiz completes this interactive lesson.
Students read an explanation of reactive power in a power distribution system involving motors, generators and transformers. A brief quiz completes the activity.
