Mechanical Engineers as an Essential Part of Production
1. Demand for qualified mechanical engineers is high. Mechanical engineers have a wide range of job opportunities. They may be management, sales, development, research, or production engineers in industries such as food, steel, chemicals, and heavy and light engineering. They also can work in service industries such as transport and gas, water and electricity.
2. Mechanical engineers are vital to the running of plants. Without them production would be impossible. Each plant is likely to be different. Some are large, some are small and most are complex. The main operational objectives of safety, efficiency and profitability are common to them all and demand a range of technical and personal skills from the engineers.
3. Mechanical engineers are concerned with machines, mechanisms and energy conversion. Mechanical equipment is at the core of the plants. Each plant is different from the next: the machines are particular to the process involved in making the end product and mechanical engineers are involved in their design, building and operation. They are at the forefront of technology: pressing the limits of material capability, developing new materials of construction, specifying complex machines and doing all of this with the most sophisticated design techniques.
4. Mechanical engineers’ jobs are demanding and exciting. Their skills, technical and managerial, are used to the fullest. In plant operation the job is to keep the plant running and stimulate the team to make better use of equipment to improve performance.
5. Mechanical engineers are at the core of production: they manage plant and equipment, they manage people. In fact, they manage our future.

Machines Through the Age
1. Mechanization, or the use of machines to do the work of animals or people, has been with us for centuries. There are six basic kinds of mechanization. Classification depends on whether machines, or combinations of animals and people, are responsible for the three fundamental elements that occur in every type of activity – power, action and control.
2. The first kind of mechanization is introduced by typing. In typing words, a body produces “the power” to drive a machine, but the machine produces “action”;
control is with the body. In the second kind of mechanization, hardware is responsible for both power and action. In car, for example, the wheels, gears and so on provide action while the engine supplies power.
3. The next 2 types of mechanized devices are all partly automatic. They are mechanically controlled; a person does not have to be present to supervise them. Simple automatic devices are not new. Soon after the first machine-tools appeared late in the 18th century, engineers modified them so that they could work by themselves fore some of the time. An operator would set his machine so that it cut a piece of metal automatically. He would not have to do anything while the operation took place. The control devices here were camshafts and stops.
4. The fifth example of mechanization is semi-automatic equipment. Here people are required for only some elements of control. In this category are lines with the conveyer systems of the 19th and early 20th centuries with which, for instance, Henry Ford’s first factories assembled cars. In this system parts move from one part of the factory to another on an automatic conveyer. But people have to be present. They stand next to the lines to fit things onto the parts as they move past.
5. Finally the sixth kind of mechanization is truly automatic devices, such as transfer lines, computer controlled machine-tools, robots. So to get a strict definition of automation, we can say: automation = mechanization + automatic control.
