Learners view an animation of a counterbalance valve in operation and examine the valve’s internal structure.
Series Circuit Analysis Practice Problems: Circuit #4
By Patrick Hoppe
In this interactive object, learners solve for the current through each resistor, the voltage across each resistor, and the power dissipated.
Thevenin Resistance: Practice Problems
Students work five practice problems to determine the Thevenin resistance of DC circuits.
The Processor Scan Cycle
By Terry Bartelt
Learners examine the three steps of a processor scan cycle.
Designing a Reciprocation Circuit
This animated lesson an exercise that enables students to design a ladder logic circuit using a drag-drop function to cause the cylinder of a hydraulic circuit to extend and retract.
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!!!
