In this animated activity, learners examine how an adjustable pressure-reducing valve can produce a pressure that is lower at its output than at its input.
The TI-83 Plus Calculator: Using Complex Numbers
By Patrick Hoppe
This primer introduces the student to the correct method of entering complex numbers in both rectangular and polar form.
Converting Values in Engineering Notation
By Ron Wallberg
The learner will convert various values to engineering notation.
Series-Parallel Circuit Analysis Practice Problems: Circuit 7
Learners solve 14 problems related to voltage, current and power in a single source, six-resistor circuit. A help screen is provided.
Series RL Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Methods of Producing Electricity
By Terry Bartelt
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.
