Unformatted text preview: single length of lumber without any waste. This, however, complicated calculations due to working with lengths with large amounts of digits after the decimal and created problems due to not having precise measurements while rounding these dimensions. Instead, the basic principles of equilateral triangles were used effectively to simplify calculations. The fact that every member was of the same length and every angle was sixty degrees made the calculations much simpler and more uniform. This also made it easy to optimize the economics of the design. The lengths of the members were set at twelve feet so there would be no waste after construction due to unusable lengths leftover from cuts. This simple equilateral design also eliminated the need to cut the members when they arrive at the job site, thus saving time and energy....
