P5.15 Determine the extension, due to its own weight, of the conical bar shown in Figure P5.15. The bar is made of aluminum alloy [E = 10,600 ksi and y= 0.100 lb/in.³]. The bar has a 2 in. radius at its upper end and a length of L = 20 ft. Assume the taper of the bar is slight enough for the assumption of a uniform axial stress distribution over a cross section to be valid. FIGURE P5.15 L X

Methods to Determine Vertical Stress

The load applied to the soil is transferred to the underground. The presence of water at soil pores and solid grains above the soil are the primary components that are responsible for the effective load transfer. Due to the load acting, the internal component of the soil or the underground formations undergoes deformations or a tectonic shift. The amount of deformation depends upon the amount of load acting on the soil surface, which indeed, depends on the weight of everything present above the soil. Due to this, the underground soil element develops internal stresses which try to resist the tectonic changes.
