Mechanics of Solids

It is the study of the behavior of solid materials, their characteristics under various circumstances such as variation in external forces, temperature, and other internal factors. It is one of most important study in the field of engineering science, especially chemistry and mechanical engineering. In rigid body, the idealization of the solid body in which deformation is neglected. Deformation is known as the force acting on the solid state system which exerts change in its shape of the body but it continues to be at rest or in a uniform motion but it cannot accelerate. But those solid systems do have elasticity, compressibility and can be bent. This field is very vast since there are wide range of materials around us.

The retained soil weighs 120 pounds per square feet, and the soil-concrete coefficient of friction, μ is 0.4. The factor of safety against overturning must be greater than 1.5, and for sliding it must be greater than 1.2. Hint: There are three weights and three moments that contribute to the stability.
