The learner will understand the design of a planetary gear drive and its advantages and disadvantages.

In a series of practice problems, learners use the addition or subtraction method to solve systems of linear equations, also called "simultaneous linear equations."

In this interactive object, learners read about the differences between push and pull manufacturing systems. A brief quiz completes the activity.

The learner will gain an understanding of the inner workings of the cycloidal gear drive while watching a video and listening to an explanation of its features.

In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.

In this interactive and animated object, learners examine the SUN VAT-40 battery starting and charging system tester. This learning object demonstrates the use of the tester in diagnosing conventional 12-volt automotive charging systems. It contains audio.

Learners review Ohm's Law and then work 12 problems to help them apply the law to automotive electrical systems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

Learners read an introduction to the four basic types of force systems for a statically determinate condition.

Explore Intrusion Detection Systems, what they are, how they're configured, and the types of protection the provide.

In a series of practice problems, learners use the substitution method to solve systems of linear equations, also called "simultaneous linear equations."

Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.

Learners examine the relationship of voltage, current, and resistance as it applies to vehicle electrical systems.

Learners review Ohm's Law and then work 12 problems to help them apply the law to automotive electrical systems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

Students follow steps to determine the number of inputs that can be driven by a specific IC. A sample problem is given.

Robotic welding is revolutionizing welder safety, efficiency, and technique. Knowing how to program a robotic welder is key in this ever-changing industry. In this module you’ll explore what Through-Arc Seam Tracking (TAST) is, discover how it works, and see it applied on the job.

In this animated activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.

Learners view an animated explanation of why an adjustment of the output voltage by an AC drive is required to maintain a constant torque as the frequency is varied.

Robotic welding allows welders to create more consistent and higher quality welds. But, it requires you to understand the terminology associated with its programs. Watch this module to review terminology associated with robotic arc welding and the weaving process.

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