Material condition modifiers may be applied to tolerances for geometric characteristics of features of size. A feature of size is one that can be measured across two opposing points, either internally or externally.

Learners read a description of the parts of an ironworker and identify them in an exercise.

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

In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.

In this animated activity, learners examine hearing and balance. Detailed drawings of the outer, middle, and inner ear structures are included.

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.

The student reads about the parts of a pipe/tubing bender and later identifies them in an interactive review.

In this interactive object, learners follow steps to program and operate the Ercolina Top Bender.

Laboratory testing begins with a doctor's order and is followed by specimen collection. In this activity, learners review doctors’ lab orders and select the blood collection tubes required for each patient.

Check your underground, subway, metro, and tube vocabulary acquisition by writing the term for each definition.
