The ultimate load capacity of a 10 m long concrete pile of square cros...
The ultimate load capacity of a concrete pile depends on several factors such as the concrete strength, the cross-sectional area of the pile, the soil conditions, and the length of the pile.

Assuming a concrete strength of 30 MPa and a conservative safety factor of 2, the ultimate load capacity of a 10 m long concrete pile of square cross section 500 mm can be estimated as follows:

- Cross-sectional area of the pile: A = 0.5 m x 0.5 m = 0.25 m²
- Ultimate load capacity: Q = A x f'c x SF
where f'c is the compressive strength of concrete and SF is the safety factor
- Q = 0.25 m² x 30 MPa x 2 = 15 MN (mega Newtons)

Therefore, the ultimate load capacity of the concrete pile is approximately 15 MN or 1500 tons. However, it is important to note that this is an estimate and actual load capacity may vary based on site-specific conditions and testing.
