In this animated activity, learners view the various hand, arm, and shoulder muscles in action. The students test their knowledge of the location of the muscles in a drag-and-drop exercise.
Records Management: Applying ARMA Rules to Business Filing
In this interactive object, learners apply their knowledge of the Association of Records Managers and Administrators (ARMA) filing rules by organizing and filing records alphabetically, numerically, and by subject.
In this animated object, learners study the rotation of the magnetic stator field of an AC motor and how it interacts with the armature to cause rotation. A short quiz completes the activity.
In this animated activity, learners study how the magnetic field of an armature can distort the DC motor's main magnetic field. A brief quiz completes the object.
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.
In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.
In this animated object, learners identify the basic parts and operation of a crank slider mechanism. They also follow the steps to use rotational input velocity to determine the linear output velocity of a slider component.
Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.
In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.
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.
Learners examine the use of the tolerances displayed in a title block by calculating the minimum and maximum allowable size of a fabricated part. In a brief quiz, students determine whether a part is usable or should be scrapped.
In this screencast, 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.
