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.
The Edison Wire System
By Terry Bartelt
Learners read a description of the wiring configuration of a residential Edison Wire System, which consists of a transformer secondary circuit. The circuit supplies two 115-volt sources and one 230-volt source.
Pneumatic Air Leaks
By Terry Bartelt, Stephen Schneider
In this animated object, learners examine the causes of air leaks and read how to repair them. The object includes audio.
Normally Open vs. Normally Closed Pressure Control Valves
In this animated activity, learners examine the operation of normally open and normally closed valves used in hydraulics. A brief quiz completes the learning object.
How Adding Parallel Branches Decreases Total Resistance
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.
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.
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.
