Students view how the tool length offsets are set on the CNC Machine. They read a description of a method that uses a 2-inch gage block as a height reference.

In this learning activity you'll explore how units in the metric system are related to each other and practice locating measurements on a metric line.

In this screencast, learners follow steps to determine the proper starting belt length for a timing, flat, or v-belt drive.

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.

In this learning activity you'll review the historical progression of standards to learn what makes a good standard.

In this interactive object, students view an animated depiction of Class 3 levers. A matching quiz completes the activity.

Students review how to use chordal distances to locate bolt hole circle locations. They then take a 10-question quiz to test their knowledge.

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.

In this learning activity you'll review the steps for calibrating the length of depth micrometer measuring rods.

In this video, you’ll explore how to set up the chuck, face your part using a left-handed and right-handed tool, center drilling, and facing the part to length.

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).

Students examine the four factors that affect resistance of a wire: temperature, length, diameter, and the type of material from which it is made. A short quiz completes the activity.

In this interactive object, learners study animal estrous cycle lengths. They then test their knowledge in three exercises.

In this learning activity you'll use the Pythagorean Theorem to calculate the lengths of the legs and hypotenuse of a right triangle.
