7.6 A dozer with as S-blade has pushed a normal load onto a level area. The height of this load measured at the inside edge of each track was 7 ft and 7.4 ft. The width of the load at the inside edge of each track was 8.1 ft and 8.4 ft. The greatest length of the pile was 16 ft. What is the capacity of the blade?

A concrete pile group 3x3 with spacing of 0.6m is used to support a wind turbine in a sand deposit. Individual pile diameter = 0.3 m and length=6m. A. If the allowable (working) lateral capacity for a single pile is 95 kN, what is the maximum allowable lateral deflection for each pile? B. Is the lateral deflection acceptable? Explain your answer in 1-2 sentences.

A square prestressed concrete pile with a 14 inch side is to be driven to the necessary depth. It needs to be able to support 105 kips. It has been determined that the point resistance qp is 120 ksf and the side friction fs is 450 psf. Use formula 12.2 (see attached image) to estimate how long the pile needs to be with a factor of safety of at least 2.5. Round your answer to a multiple of 5 feet. Use L as a variable to calculate the load in formula 12.2. L can be obtained from this equation.
