Learners consider the factors that determine how well an inductive proximity sensor can detect an object. Those factors are size, position, and the material from which the target is made. A brief quiz completes the activity.
This screencast, we see how the shape of a stain defines the angle of impact. In general terms the more circular the stain, the more perpendicular will be the angle at which it struck the surface. The more elliptical the shape of the stain, the more acute the angle will be. With practice and experience, the analyst can recognize the general angle of impact based solely on the shape of the stain.
In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied. A brief quiz completes the activity.
Students read how the Plan-Do-Check-Act Cycle is used in problem-solving and process improvement. In an interactive exercise, students organize process improvement steps following this model.
