3. They also develop power- using machines such as refrigeration and air- conditioning equipment, machine tools, material handling systems, elevators and escalators, industrial production equipment, and robots used in manufacturing. Mechanical engineers also design tools that other engineers need for their work. The field of nanotechnology, which involves the creation of high-performance materials and components by integrating atoms and molecules, is introducing entirely new principles to the design process.

7. Mechanical engineers may perform the following tasks: consider the appearance of the designs as well as the impact on the user and on the environment design new machines, equipment or systems taking into account cost, availability of materials, strength and maintenance requirements act as consultants, carrying out studies about possible changes or improvements and estimating costs of products for clients. set up work control systems (e.g. testing of equipment) to make sure that standards of performance, quality, cost and safety are met specify, select, install and manage the maintenance of factory production and machinery supervise the operation of manufacturing process plants such as vehicle and electrical appliance production plants, coal handling installations, power stations and sewerage and water supply pumping stations use Computer- Aided Design (CAD) to assist in design and drawing carry out research in the use of different types of fuel and energy, materials handling, heating and cooling processes, the storage and pumping of liquids and gases, and environmental controls undertake the design and construction of resource development projects such as offshore platforms, onshore gas plants and iron ore mining facilities
