In this animated activity, a drill-and-clamp machine is used to show an application of a pressure-reducing valve. Recommendations on how to properly make pressure adjustments are also provided.
Excel: Spreadsheet Hints
By Patrick Hoppe
Learners read how to create a spreadsheet to determine the voltage drop across a resistor in an AC circuit. The complex functions explained in other learning objects are used in this example.
Internal Elements of a 555 Timer (Screencast)
By Terry Bartelt
In this screencast, learners examine the internal elements of a 555 IC and their operation.
Series RLC Circuit Tic-Tac-Toe 2
By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased above resonance.
Series Circuit Analysis Practice Problems: Circuit #10
In this interactive object, learners solve for total resistance, total current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.
In this animated object, learners read about hydrostatic pressure and observe how it is used to measure the level of a material in a container.
By James Bourassa
In this interactive object, learners view various components of gears and read descriptions of them. Learners then identify the location of each of these components in a drag-and-drop exercise.
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.
Safety - Hydraulic Metal Shears
The learner reads about safety considerations for operating a hydraulic metal shear. Text, graphics and a brief assessment are included.
