Geometric Model, Hyperbolic Paraboloid
Geometric Model, Hyperbolic Paraboloid
Usage conditions apply
- Description
- In the late nineteenth century, a few Americans began to make geometric models like those previously imported from Europe. This string model, made by the firm of Eberbach in Ann Arbor, Michigan, is very similar to one made in Germany at about the same time. The model is adjustable. When the metal triangles lie flat, the surface formed by the strings is a rhombus. If the tips of the triangles are raised, the threads form a surface called a hyperbolic paraboloid. The model came to the Smithsonian from the Department of Mathematics at the University of Michigan.
- For another sting model by Eberbach, see 1982.0795.28.
