Students read about the concept of true power and view examples of how it is dissipated as heat is provided.
Reading a P&ID Loop
By Terry Bartelt
Learners follow steps for reading a P&ID diagram of a closed-loop circuit.
Hydraulic Brake Valves
The operation of a hydraulic brake valve, including the internal components, is presented using animations.
By Patrick Hoppe
Learners examine the concept of propagation delay within a TTL logic gate. The concept is explained with the use of timing diagrams and sample calculations.
The Firing Circuit of a DC Drive
In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.
Transformer Practice Problems
Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.
Magnetics AC Power Generation
By Tim Tewalt, Patrick Hoppe
Learners examine an animation that shows how an AC voltage is produced as an armature rotates within a magnetic field. Ten review questions complete the learning object.
Ohm's Law: Power
Learners study animated rheostat settings that show how varying the current flow affects the amount of power that is dissipated in a series circuit. Nine review questions complete the activity.
Work and Power
By James Bourassa, John Rosz
Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units. Practice problems are included.
Calculating Blank Size for Rolled Sheet Metal
By Dave Hoffman
In this interactive object, students read how to calculate the blank size for cylinders in a three-roll pinch roller. A calculator is required for the brief quiz that completes the activity.
