摘要

Two ellipses are to be fitted into a right-angled corner so that their axes are parallel to one another and also parallel to the respective sides of the corner. This problem was suggested by the requirement to design a decorative bracket. Only one quarter of the larger ellipse would actually be constructed; the smaller ellipse provides strength and, perhaps, elegance. Such a bracket is shown in figure 1. This problem is a generalization of that considered by Burley and Smith (reference 1), but only the 'easy' case in which one curve is a circle was considered in that article.
