Those tools permitted them to raise heavy loads with levers and transport them using wheels. They also used the energy in wind or falling water. Today, mechanical engineering continues to refine the fundamental concepts related to the conversion and distribution of energy, the development of vehicles of transport, the processing of materials, the automation of systems of production, the design of structures and other tasks that require the application of mechanical principles. The mechanical engineering profession offers the characteristics of flexibility, individuality, and a broad scope of problems to address. Each mechanical engineer develops a specialization, and that choice depends substantially on the individual.
Mechanical engineers are concerned about safety and efficiency of everyday mechanized equipment.
They are involved in problem solving to build a better world. Solutions to mechanical engineering problems are obtained by applying a blend of innovation, analysis, modeling, and experimentation until satisfactory results have been obtained and solutions tested. Mechanical engineers care. Mechanical engineering is essential to a wide range of activities that include the research, design, development, manufacture, management, and control of engineering systems, subsystems, and their components. Mechanical engineers use the fundamentals of engineering mechanics, energy, and thermal-fluid sciences and material sciences to design and analyze mechanical systems that perform useful tasks required by society.
