4. A tensile bar has an initial 2.000-in. gauge length and a circular cross-sectional area of 0.2 in.?. The loads and corresponding gauge lengths recorded in a tensile test are show below. After fracture the bar diameter was 0.370 in. Load Gauge length (in.)

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 comp…
