Strength of Materials: The Centroid of a Semicircle
By Steve Whitmoyer
In this animated and interactive object, learners calculate the area and centroid of a semicircle.
In this animated object, learners read about hydrostatic pressure and observe how it is used to measure the level of a material in a container.
By James Bourassa
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.
