Example 2.9 shows the calculated thickness at the bottom needed for steel plate making up the shell of a vertical-axis, flat-bottomed, atmospheric-pressure storage tank. In the United States such tanks are normally made from steel sheets either 8 or 10 ft wide, so their heights are normally multiples of 8 or 10 ft. The 60-ft-high tank in that example would be made of 6 bands, one atop the other, each made of steel sheets 10 ft wide, each with its own uniform thickness. The lowest band would have the thickness calculated in Example 2.9. a) What would the required thickness be for the remaining bands above the bottom band
