In this animated activity, learners examine how an adjustable pressure-reducing valve can produce a pressure that is lower at its output than at its input.

Dental x-rays are generated in the dental x-ray tube. Through this animated learning object, students will learn the steps in x-ray generation from turning on the x-ray unit to exposing the dental x-ray film.

In this document you'll review drill press work-holding devices.

The learner will understand the two methods used to create a phase shift in current between two windings.

The learner reads an explanation of how to determine lengths for tubing and pipe bending and then performs calculations in an interactive exercise. Two methods for determining angle bends are shown. A calculator is required.

Identifies the parts of the hydraulic press brake featuring the Adira up-acting press brake. Interactive section asks to identify parts after first learning them.

In this learning activity you'll examine how logical addresses work. The IP address is the logical address assigned to a connection by the ISP or network administrator.

Learners examine the function of the analog wattmeter to measure true power, how it is connected in a circuit, and how the internal components develop a measurement. A brief quiz completes the activity.

In this animated activity, learners examine how various NAND gate configurations and the logic signals produced throughout the circuit perform the functions of all of the other types of logic gates.

Students read step-by-step instructions for determining the square root of a number using the TI-86 calculator.

Students read about the ENTRY, INS, and DEL keys and view a demonstration of how to edit and insert characters and recall previous entries.

This project gives a drawing with steps to complete the activity.

This project gives the student a drawing and steps to complete an activity.

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

In this animated object, learners examine the basics of capacitance and capacitors.

Students follow steps to determine the number of inputs that can be driven by a specific IC. A sample problem is given.

In this learning activity you'll review the operation of a NOR gate by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

Learners examine the theory of operation for a combustible gas detector. A brief quiz completes the activity.

Learners read an introduction to the four basic types of force systems for a statically determinate condition.

This animated lesson shows how a pressure switch connected in a ladder circuit causes the cylinder of a hydraulic circuit to extend and retract.

In this animated activity, learners examine the components of the dental x-ray tube and how dental x-rays are generated.

In this animated object, learners examine the operation of a demultiplexer along with the data output and select lines. A brief quiz completes the activity.

In this learning activity you'll review how a local area network computer uses a subnet mask to determine if its message is intended for a computer on the same network or on a remote network.

In this learning activity you'll examine the format of an IP address and interpret the octet by converting between decimal and binary numbers.

This document is a visual and text description of tapers and radii on a lathe.
