By Terry Bartelt, Stephen Schneider
In this animated object, learners examine the internal structure of an unloading valve. This learning object includes a video clip demonstrating the use of an unloading valve in a metal stamping application.
Hydraulic Cylinder Speed
In this interactive and animated object, learners examine why the piston of a hydraulic cylinder extends slower than it retracts. A brief quiz completes the activity.
In this animated and interactive object, learners examine the interaction between a conductor that represents a motor armature and a magnetic field that represents a motor’s main field. This interaction causes the shaft to turn.
Analog Position Control
In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.
By Barbara Anderegg
After a brief review, the student solves five practical shop problems using right angle trigonometry.
Transistor DC Analysis Practice Problems: Circuit #1
Learners analyze a base-biased npn transistor circuit. A "help" screen is available.
Difference Op Amp
Learners examine the fundamental operation of a difference operational amplifier. A brief quiz completes the activity.
Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.
In this animated activity, learners examine how an electronic converter changes digital signals to analog signals. Sections of a synthesizer are identified, and the operation of a D/A converter is demonstrated.
Conductors, Insulators and Resistors
In this animated activity, learners examine why various materials are conductors, insulators, or resistors of current. A short quiz completes the learning object.
Current in a Series Circuit
