In this animated activity, users examine the causes of malfunctions in a hydraulic pressure-reducing valve and the problems that result. A short quiz completes the learning object.
Electrical Switches & Pushbuttons
By Terry Bartelt
In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.
The Three-Phase Motor Stator Field
In this animated activity, learners study how stator poles create a rotating field in a three-phase AC motor as a three-phase AC voltage is applied.
In this learning activity you'll determine the voltages that can be topped off of a multi-resistor voltage divider that has one main power source.
Thevenin Resistance: Practice Problems
By Patrick Hoppe
Students work five practice problems to determine the Thevenin resistance of DC circuits.
Methods of Producing Electricity
In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
How Pressure Changes Boiling Temperature
By Terry Bartelt, Terry Fleischman
Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.
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.
