The learner will understand proper safe handling and installation procedures for shielding gas cylinders.

Learners follow the progression of a sexual harassment situation and recount the steps the victim took to deal with the problem.

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

In this learning activity you'll test your knowledge of angular measurement in this 10-question quiz.

In this animated object, students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.

In this animated object, learners examine the situation that occurs when any two links of a mechanism lie in the same plane or on a straight line. Crank-sliders and crank-rockers are shown.

Learners study how a circuit converts the AC output of a linear voltage differential transformer (LVDT) into variable DC voltage. It is recommended that learners view the learning object IAU7807, “The LVDT: A Linear Voltage Differential Transformer in Action” before going through this object.

In this interactive object, learners examine problem areas related to patients with arthritic conditions. They also identify treatment precautions and design a treatment plan.

In this interactive object, the learner reads an explanation of how various shielding gases are used in GMAW and FCAW. An exercise completes the activity.

This game will help people to understand linear equations with one variable and at the same time have fun
