Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.
Synchronous Speed of an AC Motor
By Terry Bartelt
In this animated and interactive object, learners study the synchronous rotational speed of the magnetic field created by the stator of an AC Motor.
Power Law Practice Problems #3
By Patrick Hoppe
Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.
Series-Parallel Resistance -- Practice Problems
In this learning activity you'll practice solving for the total resistance of series-parallel DC circuits.
Three-Phase Delta Transformer Calculations
By James Bourassa
Using a memory shortcut for calculations, the learner determines line and phase values of current in a three-phase AC configuration. Practice problems complete the activity.
Identifying Lever Classes
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.
Brain Exercise: Visualization #3
Learners develop 3D visualization skills by examining front, side, and top orthographic views of objects. Using this information, students select the corresponding isometric view of each object.
