This animated lesson shows how pushing a start or stop button on a ladder circuit causes the cylinder of a hydraulic circuit to extend and retract.
In this learning activity you'll calculate percentages, cumulative percentages, and answer questions related to sample Pareto charts.
In this learning activity you'll review the steps for calibrating the length of depth micrometer measuring rods.
This project gives steps to complete the activity.
Students read about the edge-finder's parts and assembly, and view video clips of the tool in action.
NOTE: Because of the video clip, this object is a large download. (2.6mb)
In this learning activity you'll review a drawing and steps to complete an activity.
In this learning activity you'll review a visual overview of depth measurement using the depth micrometer.
The learner solves for Zin(base), Zin(stage), Zout, and Av. A "help" screen is available.
Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.
In this animated object, learners examine the operation of a Schmitt Trigger IC and its hysteresis function. A brief quiz completes the activity.
In this interactive object, learners set up a shear, enter the back gauge dimension, and prepare to shear metal in a simulation of the Adira Hydraulic Shear.
Students read an explanation of the common-source and source-follower amplifiers. Gain formulas are developed and an example is given.
Students follow steps to transfer data from a list to a histogram.
Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.
Learners listen to an explanation of how to perform an inventory of a farm business. They then list their hard assets and human resources by completing worksheets that they save to their personal computers.
Students take a 13-question quiz to practice reading 25- and 50-division Vernier height gages.
