Foundation piles 1

Four 12 inch diameter piles (each of whose frictional capacity is 300 psf) support a column carrying 120 kips total load.

What is the frictional area required for each pile?
A. 30 sf
B. 40 sf
C. 70 sf
D. 100 sf

AnswerD. 100sf. Each pile supports 30 kips (120 kips / 4), when divided by the frictional capacity (30 kips / 0.300 kips per sf = 100 sf) gives the required frictional area 100 sf
