Among various recent trends in the engineering profession computerization is the most widespread. The trend in modern engineering offices is also towards computerization. Computers are increasingly used for solving complex problems as well as for generating, storing and handling the enormous volume of data modern engineers must work with.
Scientific methods of engineering are applied in several fields not connected directly to manufacture and construction. Modern engineering is characterized by the broad application of what is known as systems engineering principles.
Engineers in industry work not only with machines but also with people, to determine how machines can be operated most efficiently by workers. A small change in the location of the controls of a machine or of its position with relation to other machines or equipment, or a change in the muscular movements of the operator, often results in greatly increased production. This type of engineering work is called time-study engineering.
A related field of engineering, human-factors engineering, also known as ergonomics, received wide attention in the late 1970s and 1980s when the safety of nuclear reactors was questioned following serious accidents that were caused by operator errors, design failures, and malfunctioning equipment.
Human-factors engineering seeks to establish criteria for the efficient, human-centred design of, among other things, the large, complicated control panels that monitor and govern nuclear reactor operations.

Computer engineering now the most rapidly growing field. The electronics of computers engineers in design and manufacture of memory systems, of central processing units, and of peripheral devices. The field of computer science closely .... computer engineering; however, the task of making computers more intelligent (artificial intelligence). Microminiaturization .one of the current trends in computer engineering. During many years engineers . to place greater and greater numbers of circuit elements onto smaller and smaller chips. Another trend towards increasing the speed of computer operations through the use of parallel processors and superconducting materials.

1) Is of reddish colour and has corrosion resistant qualities. Also is the best conductor of electricity.
2) A silvery metal which is not corroded by air. It is used for making tin plate.
3) A very expensive metal. A grey malleable metal used for roofing and battery plates, pipes.
4) Its color is yellow when hot and white when cold. It is used for making dry batteries.
5) Malleable ductile silvery-white metal. It is widely used for structural and engineering purposes.
6) The best known light metal. It does not rust in the air. It is soft and that is why it is used only when alloyed with other metals.
