In a way, mechanical engineers are involved in creating the future. They are the driving force behind many of our technologies and industrial processes including innovative products like mobiles, PCs and DVD etc in our modern world. The work of a Mechanical Engineer can be extremely challenging and fulfilling, requiring IT, design and analytical skills together with an ability to work as a team. As their work involves production, transmission and use of mechanical power and heat, they have to analyse the different materials used for the machines and their tolerances, investigate the different energy sources and the power they generate and the design problems if any. When designing and making a commercial product they have to take into account all the business and marketing aspects to make sure that the product is affordable. They share interests with many other engineers like Civil Engineers in structures and stress analysis; Electrical engineers in electronics, computing and control theory; Aeronautical Engineers in fluid flow and turbomachinery etc and also design tools needed by other engineers for their work. They work as part of a team with other engineers as well as financial, business and management professionals on a project together. Mechanical Engineers are also responsible for maintenance and repair of the devices. Care has to be taken that the plants give maximum output and the machinery is properly maintained.
The specialisations include in areas like thermal engineering, design, and production engineering etc. Mechanical engineers work mainly in manufacturing firms. They can find work in administrative and managerial positions in government departments or public and private sector industries or do research as well as teaching in Research and teaching institutes. They could also opt for technical sales / marketing or work as independent consultants
