Basics of Mechanical Engineering Design

The word mechanical engineering design consists of two words, mechanical engineering, and engineering design. Mechanical engineering deals with the design and analysis of mechanical systems and components using the laws and principles of mechanics and physics. On the other hand, engineering design deals with determining the dimensions of the components or members under the action of external influences such as loads to make it fail-safe. Engineering also deals with determining the maximum and safe limit of loads and stresses that can be exerted on a body without causing the component to fail. In the domain of mechanical engineering, design is restricted to determining the permissible safe dimensions and loads that can be applied to the component without causing it to undergo fractures or deformations. Mechanical engineers are primarily in charge of the design and analysis of the mechanical components of a system under static and dynamic conditions.
