 After having had several drawings of the faces of oblique arches made on a large scale and projected with great exactitude, we observed that the following remarkable property exists. If the lines, which are the chords of the small curves forming the...  A Practical and Theoretical Essay on Oblique Bridges - Page 6by George Watson Buck - 1839 - 43 pagesFull view - About this book
