A reinforced cement concrete pile weighing 30 kN (including helmet and dolly) isuriven by a drop hammer weighing 30 kN with an effective fall of 0.9 m. The average pen- etration per blow is 15 mm. The total temporary elastic compression of the pile, pile cap and soil may be taken as 18 mm. Coefficient of restitution 0.36. What is the allowable load on the pile with a factor of safety of 2? Use Hiley's formula.
