Application of Hyperboloid of One Sheet in Real Life

The curved surface generated by a family of rectilinear motion is called ruled surface in geometry, and the straight line in motion is called rectilinear generator. Hyperboloid of one sheet is exactly a typical ruled surface, which has two families of rectilinear generator. This paper probes into the application of hyperboloid of one sheet in constructional engineering, electric power engineering, mechanical processing, communication engineering and daily life, and further studies the method of making hyperboloid of one sheet by hand.
