WebThe arch calculator calculates the distance [G] between the focus points [F] and the arch's center [C] (see Elliptical Point Measurements diagram below). This distance is determined based on the arch's height [H] and width [K]. Before using this calculator, you must know the height [H] and the width [K] of the arch that you are wanting to build. WebHoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt.
