In this learning object you'll explore wheel markings identifying the major factors in grinding wheel selection.

In this interactive object, learners examine simplified sampling plans and tables based on the ANSI/ASQ Z1.4 standard. An exercise completes the activity.

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.

In this learning activity you'll calculate percentages, cumulative percentages, and answer questions related to sample Pareto charts.

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.

Learners complete a matching exercise as a quiz or as a review of state laws and rules pertaining to barbers and cosmetologists.

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.
