Learners examine the differences and similarities between hydraulic and pneumatic systems.
Instantaneous Current Calculations of an Energizing RL Circuit (Calculator TI-30XIIS)
By Terry Bartelt
Students view the keystrokes of a TI-30XIIS calculator that are required to solve for the instantaneous current of an energizing RL circuit.
Basic Types of Lines Used in Engineering Drawings
By Kelly Curran, Glenn Sokolowski
In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.
Integral Reset Setting
Learners study animations showing the integral function of a closed-loop control system and the difference between the two types of integral controller settings, reset rate and reset time. A short quiz completes the activity.
Light-Emitting Diodes (LED)
By Patrick Hoppe
Students read about light-emitting diodes, including LED voltage and current, and how to protect against reverse voltage.
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.
