Learners examine the differences and similarities between hydraulic and pneumatic systems.
Labeling DC Motor Connections
By Terry Bartelt
Learners examine the connections of a DC motor and how the terminals are labeled. A matching exercise completes the learning object.
Motor Control Circuits
Learners examine an electric motor control circuit that uses a motor starter module. This activity has audio content.
The Shunt Motor Open Field
In this animated object, learners observe the changes inside the DC shunt motor that could cause the motor to break apart when its field coil opens. A short quiz completes the activity.
Transformer Practice Problems
By Patrick Hoppe
Students solve practice problems on voltage, current, and impedance matching. Examples precede the problems.
The Multiplication of Force by a Hydraulic System
In this animated and interactive object, learners examine a depiction of how force is multiplied by a larger cylinder when pressure from a pump is applied to a smaller cylinder. A short quiz completes the activity.
Pascal's Law and Hydraulics
Using the principle of Pascal's Law, the learner will interpret the gauge readings in a hydraulic system to determine when the system is operating properly under various load conditions and when there is a defect.
The Hydraulic System
Examine the components of a hydraulic system.
The Hydraulic Pressure Switch
This animated lesson shows several ways that a hydraulic pressure switch, connected in a ladder circuit, causes the cylinder of a hydraulic circuit to perform various applications.
By Terry Bartelt, Stephen Schneider
In this animated activity, learners examine how cavitation occurs in a hydraulic pump. A video clip is included. Learners then test their knowledge in a brief quiz.
