uniform timber pile which has been driven to a depth L in
clay carries an applied load F at the top. This load is resisted entirely by friction f along the pile which varies in the parabolic manner f=ky^2.
a) Determine the total shortening of the pile in terms of F, L, A,
and E;
b) If F=96 kips, L=40 ft., A=100in2, and E=1.5 x 106 psi, how
much does such a pile shorten?
