Basic Symbols Used in Engineering Drawings
By Kelly Curran, Glenn Sokolowski
Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.
DC Current Flow Through a Parallel Circuit
Learners observe current flow throughout the series portion and branches of a parallel circuit. This animated activity includes calculations and a short quiz.
Voltages Across Series and Parallel Capacitive Circuits
In this interactive and animated object, learners examine how dc voltages develop across capacitors that are connected in series and in parallel.
Comparing Electronic and Hydraulic Components
Learners read about the similarities of electronic and hydraulic components and then match the schematic symbols in a drag-and-drop exercise.
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.
The Processor Scan Cycle
Learners examine the three steps of a processor scan cycle.
The Variable Reluctance Stepper Motor
Learners view colorful animations showing the operation of a VR stepper motor.
Analog Position Control
