In this interactive object, students calculate inductive reactance, impedance, current, and power in parallel RL circuits.
By Terry Bartelt
In this learning activity you'll describe the operation of an AND gate by using a truth table, a waveform diagram, a Boolean Algebra equation, a switch analogy, and a written definition.
By Terry Bartelt, Stephen Schneider
Learners view an animation of a sequence valve in operation and examine the valve’s internal structure.
Series-Parallel Circuit Analysis Practice Problems: Circuit 3
By Patrick Hoppe
In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.
Title Block Tolerances
By Glenn Sokolowski
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.
The Vertical Portion of the Sine Wave
In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.
The Horizontal Portion of the Sine Wave
In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.
Series-Parallel Practice Problems Circuit 4
In this interactive object, learners work 12 problems dealing with dc circuit analysis.
Basic Types of Lines Used in Engineering Drawings
By Kelly Curran, Glenn Sokolowski
In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.
Basic Symbols Used in Engineering Drawings
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.
