In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.

In this learning activity you'll practice reading an inch micrometer.

The learner will gain an understanding of how a robot uses welding instructions to perform tasks. This learning activity includes video.

Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.

The learner reads step-by-step work instructions and views a drawing for facing and center drilling on a lathe.

Learners analyze an emitter-biased npn transistor circuit. A "help" screen is available.

Students read an introduction to inductive reactance and view examples.

In this document you'll review the Sterling Drill Grinder.

In this animated object, learners drag resistors of the proper value into a series circuit to cause a required amount of current to flow. Seven review questions complete the activity.

Explore repetition structures, which are commonly referred to as “Looping” statements, are a vital component of programming computer and industrial applications.

A sample exam for DC/AC I, unit # 12 is presented to the students. This unit covers transformers.

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.

In this interactive object, learners examine how voltages and currents vary in a parallel LC circuit as the applied frequency changes.

Instructions on how to interpret state indicator symbols for input and output terminals of digital devices is presented.

In this interactive object, learners set up a shear, enter the back gauge dimension, and prepare to shear metal in a simulation of the Adira Hydraulic Shear.

The learner sees photos of the spark patterns of various materials and their related properties.

In this interactive object, learners view various components of gears and read descriptions of them. Learners then identify the location of each of these components in a drag-and-drop exercise.

In this learning activity you'll review a visual overview of inside measurement.

Let's explore what 5S is and how we use it in the welding workshop.

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.

In this interactive object, learners work 10 problems covering resistors, voltage, and current.

In this interactive object, students answer 10 questions covering Ohm's Law and Power Law.
