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.

Learners view wire feed power sources ranging from 110-volt, single phase units to 460-volt, three-phase units. A description and photos of each are provided.

Using this learning object, students will be able to assess their knowledge of cylindrical grinder components.

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

In this learning activity you'll examine a stateful packet inspection firewall that keeps track of legitimate Internet service requests, also known as dynamic packet filtering.

Learners review the process for calculating board feet and use virtual samples to practice the process.

Learners read how to use a lumber rule to quickly and accurately estimate board feet. They then use virtual samples to practice the process.

In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).

A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.

Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.

This is an animated troubleshooting exercise that takes voltage measurements to determine the fault of three different series circuits. There are six review questions that enable the learner to determine the effectiveness of the troubleshooting presentation.

You'll practice converting between units of measure for length in the metric and English measurement systems.
