Mechanical Engineering is a diverse and dynamic field that involves the design, development, manufacturing, and maintenance of mechanical systems
and devices. Mechanical engineers work on a wide range of projects, from designing components for consumer electronics to developing machinery
for industrial processes. It is one of the oldest and broadest fields of engineering, and is responsible for the development of many of the
physical systems and technologies that we use in our daily lives.Mechanical engineers use a combination of mathematical and scientific principles,
along with computer simulations and physical prototypes, to design and test mechanical systems. These systems can range from small devices and
instruments, to large industrial machinery and vehicles.In the field of mechanical engineering, there are many specialized areas, such as robotics,
automotive engineering, aerospace engineering, and renewable energy systems. Mechanical engineers play a crucial role in advancing technology
and improving efficiency in various industries.
Sub-fields of Mechanical Engineering:
1.Mechanics of materials (stress, strain, and deformation of solids)
