In this interactive object, learners are given the RPM, the pulley diameter, and the force, and proceed to calculate belt velocity and horsepower.
The Closed-Loop Velocity Servo System
By Terry Bartelt
In this animated object, learners examine the operation of a closed-loop system that maintains the speed of a conveyer belt as heavy boxes are placed or removed.
The Electrostatic Charge of a Capacitor
In this animated activity, learners examine the conversion of electrical energy into an electrostatic charge within the dielectric material of a capacitor.
Impedance: Series to Parallel Conversion
By Patrick Hoppe
Students view the formulas to be used to convert a series impedance to a parallel impedance.
De-Energizing Time Constants of an RL Circuit
In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A 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
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.
