Why is Varignon's theorem important? It allows us to negate the actual weight of the truss members in truss analysis. O None of these are are correct O It allows us to compute the moment of a force by taking the moment of the force's components. O It permits us to assume every member in a truss is a two-force member. O It allows us to take a moment at any point along the line of action.

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.
