The limit equilibrium methods use Mohr-Coulomb expression to evaluate the shear strength along with the sliding surfaces. The shear stress the soil fails is referred to the shear strengths of the soil. The limit equilibrium state exists when the mobilized shear stress is expressed as the fraction of shear strength. The shear strength is mobilized fully at the moment of the failure along with the failure surfaces when the critical conditions state is reached. Thus, the shear strength is expressed usually by the Mohr-Coulomb linear relationship and the Ʈ and Ʈf are defined by: Φ, c and a = friction angle, cohesion and attraction in stress terms F= factor of safety

The shear strengths rely on the effective normal stress and type of soil. The mobilized shear stress relies on the external forces that act on the soil mass. The factor of safety is the ratio of Ʈ and Ʈf in the limit equilibrium analysis. The factor of safety can be explained in three ways: moment equilibrium, force equilibrium and limit equilibrium. The first definition describes that the shear strength can be obtained in two ways: effective stress approach and total stress approach. The type of strengths relies on the loading condition, time elapsed after the excavation and type of soil. The total stress strength is commonly used for the short-term conditions in the clayey soils and the effective stress strength is commonly used in the long-term conditions in all types of soils. The second definition is based on the force equilibrium, and the third definition is based on the movement equilibrium. The second and third definition can be confusing sometimes whether the moment or force is a contribution on driving or resisting sides. For example, the force components along the sliding surface are considered on the resisting sides as the positive contribution as it increases the capacity of resistance against the movement. On the other hand, the component can be considered on the driving side as the negative contribution as it diminishes the driving tendency. The slices weights are situated at the tow and considered either on the driving side as the negative contribution or on the resisting side as the positive contribution.

Global demand for soybeans has seen tremendous increase in the recent set of years, with China being the only country that is leading in the production of it. Nearly 60 percent of soybeans that are in the international trade are towards China.

The soybean was initially domesticated in eastern China by the farmers belonging to that place which ended up after the 2nd world war. Rice, Wheat and corn were the agricultural leads that were the leading crops. Soybeans also were included in the list from then, which increased the demand for it.

Soybean was researched and found to have more nutritious values which were included in the poultry farms where it was used in parts along with the feed ratio of other grains. Soybean meal turned out to be very popular because of the poultry industry.

China’s wanted to turn against the exports from its place so that the focus more would be on its own economical growth. The higher demand to rise the own standards of the public in china, the small foods were exported to get more money which included Tofu, Oil and feed sea foods.
