In detection of a defect in a part of an object having a surface which is substantially a surface of revolution, the surface of the inspected part is illuminated by light rays which are emitted through an annular portion coaxially disposed with the surface of the inspected part, and light rays reflected at the surface of the inspected part are received to form an image of the inspected part. The i...

At least two generally parallel compression rims are joined by tension element spokes, such as cables. A rim separating means, such as columns, holds the rims apart thus maintaining spoke tension. The resulting structural element, comprising rims, tension elements and separating means, becomes an efficient means of transferring external forces from one rim to the other.
