In this interactive object, students view an animated depiction of Class 3 levers. A matching quiz completes the activity.
Sizing Motor Overloads
By Terry Bartelt, Pat Jensen
Learners use the National Electrical Code to determine the size of a motor overload protection device.
Op Amp Fundamentals: The Transconductance Amplifier
By Patrick Hoppe
Students read an introduction to the transconductance amplifier. They also view formulas for voltage-to-current conversion, closed-loop input, and output impedance. An example of how R1 controls the conversion factor is given.
The Frequency of an AC Generator
By Walter Hedges, Terry Bartelt
Learners study the factors that determine the frequency of an AC generator, such as the rotational speed of the armature or the number of stator poles.
Torque Sequence of Two Mating Surfaces
By James Bourassa
In this interactive object, learners demonstrate the proper tightening sequence for mechanically joining two mating surfaces.
Identifying Lever Classes
In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.
Calculating Horsepower, RPM, and Torque
By James Bourassa, John Rosz
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.
Brain Exercise: Visualization #1
In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object. Front, side, and top orthographic views are shown.
Brain Exercise: Visualization #3
Learners develop 3D visualization skills by examining front, side, and top orthographic views of objects. Using this information, students select the corresponding isometric view of each object.
