Learners view an animation of a counterbalance valve in operation and examine the valve’s internal structure.
Hydraulic Cylinder Speed
By Terry Bartelt
In this interactive and animated object, learners examine why the piston of a hydraulic cylinder extends slower than it retracts. A brief quiz completes the activity.
Weight- Volume Relationships: Saturated Density (Metric)
By Steve Whitmoyer
Students read how to determine and calculate the saturated density for a given sample of soil or aggregate, based on the mass-volume relationship. Practice problems complete the activity.
The Dynamic Response of a Closed-Loop System
Learners examine the factors that contribute to the delays in the response time throughout a closed-loop system.
Basic Types of Dimensioning Used in Engineering Drawings
By Kelly Curran, Glenn Sokolowski
Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.
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.
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).
Calculating Bend Allowance for Press Brake Forming
Introduces two methods of determining bend allowance; one is simple and is an approximate, the other is more precise. Interactive part has learner calculate bend allowance and blank size.
The initial illustration shows a cylinder that needs to EXTEND to raise the load! However, the remainder of the example shows a cylinder that must RETRACT to raise the load!!!
