Mechanics It is defined as that branch of science, which describes and predicts the conditions of rest or motion of bodies under the action of forces. Engineering mechanics applies the principle of mechanics to design, taking into account the effects of forces. Statics Statics deal with the condition of equilibrium of bodies acted upon by forces. Rigid body A rigid body is defined as a definite quantity of matter, the parts of which are fixed in position relative to each other. Physical bodies are never absolutely but deform slightly under the action of loads. If the deformation is negligible as compared to its size, the body is termed as rigid. Force Force may be defined as any action that tends to change the state of rest or motion of a body to which it is applied. The three quantities required to completely define force are called its specification or characteristics. So the characteristics of a force are: 1. Magnitude 2. Point of application 3. Direction of application 1
