The learner will gain an understanding of robot motion control by comprehending the fundamentals of the encoder.

Students read how to set up the optical comparator edge detector in this interactive learning object.

Step-by-step of setting the back gauge with an Adira Hydraulic Shear.

In this animated and interactive object, the learner uses a TI-86 calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.

In this learning activity you'll apply the Pythagorean Theorem to isosceles and equilateral triangles.

In this animated object, learners examine the properties of the hydrogen bond and how the bond changes when hair is shampooed or styled.

This learning object shows 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.
