The operation of a hydraulic brake valve, including the internal components, is presented using animations.
Energizing Time Constants of an RL Circuit
By Terry Bartelt
In this animated object, students view an explanation of how current, voltage, and the magnetic field strength of a series RL circuit change during five time constants. A brief quiz completes the activity.
Series RC Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
The Time-of-Flight Flowmeter (Screencast)
Learners view animations showing how a time-of-flight flowmeter uses ultrasonic sound waves to measure the flow of a liquid.
Deriving the Formulas of the Power Wheel
By Ron Wallberg
Use Ohm's law, Watt's law, and the power equation to derive formulas for the DC power wheel.
Brakes: Measuring Brake Drums
By Ken Kempfer, Dan Claus, John Hadjikyriacos, Kevin Guthrie
Learners examine the proper way to set up standard and metric micrometers to measure the wear on a brake drum.
Hydraulic Directional Control Valves
In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.
The Spring-and-Diaphragm Actuator
Learners study an animation of a spring-and diaphragm actuator controlling the opening of a flow valve.
Learners examine how air-to-open valves and air-to-close valves are used in different situations. A brief quiz completes the activity.
Shear - Hydraulic - Adira - Operator's Panel
By Dave Hoffman
Picture of Adira hydraulic shear's operator's panel with part identification and instructions on how to start and stop the shear as well as setting stroke (cutting length).
