S3 =S2 + ~2 =0.134 + 0.113 =0.247 cm. 11. Now from (1' - s) curve, Fig. Ex. 15.26 l' = 0.55 kg/cm2 for s3 = 0.247 cm. This is the

maximum shear stress. 12. Now the pile load in segment 3 is

Q3 =4 x 30 x 600 x 0.55 + 35,460 =39,600 + 35,460 =75,060 kg 13. The compression of segment 3 is

~s = Q3~ = 75,060 x 600 = 0.238 cm 3 AE 900x21xl04 .
