Answer:
hello your question is incomplete attached below is the complete question
answer : 0.75 ( A )
Explanation:
Given data:
12 - in diameter pile
embedded 50-ft
type of soil ; clay
Cohesion = 1000 psf
Determine the Ultimate pile Capacity
cohesion = 1000 psf
hence 1000 psf = 1 ksf (where ; 1 psf = 0.0.001ksf )
form the given table the value of α corresponding to 1 ksf = 0.75
