In this document you'll review photos of different types of drilling tools.

In this learning activity you'll review different types of steel rules used in manufacturing.

In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

In this animated and interactive object, learners examine the voltages that develop across two series zener diodes, which are connected in opposite directions, when DC and AC voltages are applied across them. A brief quiz completes the activity.

Learners examine the accounting process of recording, classifying, summarizing, interpreting, and communicating.

In this interactive object, students calculate inductive reactance, impedance, current, and power in parallel RL circuits.

Learners examine the proper way to set up standard and metric micrometers to measure the wear on a brake drum.

In this animated object, learners examine the bones of the appendicular skeleton.

In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.

You'll practice calculating and selecting the proper cutting speeds for various drill press operations.

You'll practice defining terms related to spheres and identifing parts of spheres.

You'll become familiar with some common medical abbreviations.
