The Danish pile-driving formula is to be used for field control of a pile installation. Steel pipe piles penetrating approximately 40 ft are to provide a design capacity of 60 tons. Each pipe has a net cross-sectional area of 20 in.2(a) What should be the set under the last blow of an ICE Model 115 hammer to obtain the desired axial capacity?(b) What set is required by the Gates formula?
