Mechanical design is the process of creating and developing mechanical systems and components. It involves applying principles of physics and engineering to design machines, tools, and devices that meet specific requirements. Mechanical designers use computer-aided design (CAD) software to create detailed drawings and models, ensuring that parts fit together and function properly. The field encompasses various areas, including automotive design, aerospace engineering, and consumer product design. Mechanical designers must consider factors such as materials, manufacturing processes, and safety standards. Their work is essential in producing reliable and efficient products that enhance everyday life and industrial operations.
