In this interactive object, students view an animated depiction of Class 2 levers. A matching quiz completes the activity.
The Three-Phase AC Generator
By Terry Fleischman
In this 3D animated object, learners examine the way in which a three-phase generator produces three sine waves with three armature coils. A quiz completes the activity.
Calculating DC Values of a Transistor Amplifier
By Terry Bartelt
In this animated activity, learners view the seven steps that are used to calculate voltage and current values throughout a common-emitter transistor amplifier.
The Duty Cycle of a Multivibrator
In this interactive and animated object, learners examine the duty cycle of a squarewave produced by a multivibrator using a 555 IC (integrated circuit). A brief quiz completes the activity.
The Reynolds Number
In this animated learning object, users study the factors that affect a pipe’s fluid flow and how those factors pertain to a numerical value (the Reynolds Number).
How Pressure Changes Boiling Temperature
By Terry Bartelt, Terry Fleischman
Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. 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.
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.
