Learners examine the differences and similarities between hydraulic and pneumatic systems.
By Terry Bartelt
Studies show that more than 75 percent of all hydraulic system failures are a direct result of unclean oil. In this interactive object, learners examine the three primary types of hydraulic system filters. A brief quiz completes the activity.
Converting Rotational Velocity to Linear Velocity
By James Bourassa, John Rosz
In this animated object, students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.
Total Resistance of a Series Circuit
By Patrick Hoppe
In this learning activity you'll review the process of solving for the total resistance in a series DC circuit.
Calculating DC Values of a Transistor Amplifier
In this animated activity, learners view the seven steps that are used to calculate voltage and current values throughout a common-emitter transistor amplifier.
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.
