Learners examine the differences and similarities between hydraulic and pneumatic systems.
The Purge Level Measurement Method
By Terry Bartelt
In this animated object, learners examine how the purge pressure system is used to measure levels of material. A brief quiz completes the activity.
RPM of AC Motors
By Terry Bartelt, Terry Fleischman
Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.
Statics - Trig: The Pythagorean Theorem Using a TI-36XCalculator
By Steve Whitmoyer
In this animated and interactive object, the learner uses a TI-36X calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.
Series-Parallel Circuit Analysis: Practice Problems Circuit 1
By Patrick Hoppe
In this interactive object, learners analyze a series-parallel DC circuit problem in a series of steps. Immediate feedback is provided.
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.
