This interaction tests the student's knowledge of fixed gages.

This video shows how to measure the inside diameter of a part using telescoping gages.

This video shows how to measure a hole diameter of a part using small hole gages.

The learner will define indirect measurement, identify common indirect measuring tools, and select the proper measuring tool for the situation.

Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.

Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.

Students use trigonometry to find the coordinates of the blending point where a line and an arc meet. Learners are given the coordinates of the center of the arc, the radius of the arc, and the direction of the line.

In this animated and interactive object, learners examine the definitions and formulas for radius, diameter, circumference, and area. Students also solve practice problems involving the circumference and area of a circle.

Students take a 13-question quiz to practice reading 25- and 50-division Vernier height gages.

In this module we will explore some commonly used formulas for area and volume.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

Students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.
