In this interactive object, students view an animated depiction of Class 2 levers. A matching quiz completes the activity.
The RC Time Constant
By Patrick Hoppe
Learners examine the concept of the RC time constant. The instantaneous voltage across the capacitor is calculated.
Calculating Belt Velocity and Horsepower
By James Bourassa, John Rosz
In this interactive object, learners are given the RPM, the pulley diameter, and the force, and proceed to calculate belt velocity and horsepower.
Impedance: Parallel to Series Conversion
Students view the formulas to be used to convert a parallel impedance to a series impedance.
Single-Phase Motors: Introduction to Phase-Splitting
By Terry Bartelt, Terry Fleischman
Learners will understand how the interaction of the armature magnetic field and the rotating stator field cause the rotor of a single-phase AC motor to turn.
How Pressure Changes Boiling Temperature
Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.
Identifying Lever Classes
By James Bourassa
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
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.
