Two solid bars support a load P as shown. Bar (1) has a cross-sectional area of A1 = 3450 mm2 and an allowable normal stress of 65 MPa. Bar (2) has a cross-sectional area of A2 = 3300 mm2 and an allowable normal stress of 120 MPa. Assume x1 = 2.1 m, x2 = 3.4 m, y1 = 0.8 m, and y2 = 2.5 m. Determine the maximum load Pmax that can be supported by the structure without exceeding either allowable normal stress.

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.
