Скачать или смотреть Axial Load & Normal Stress Example Problem with Self Weight

Axial deformation example problem including self weight and requiring the calculus version of the axial load equation to find the maximum average normal stress in the pipes and elongation of its free end. Weight per unit length acts similar to a distributed load.

The A-36 steel drill shaft of an oil well extends 12,000 ft into the ground. Assuming that the pipe used to drill the well is suspended freely from the derrick at A, determine the maximum average normal stress in each pipe string and the elongation of its end D with respect to the fixed end at A.
