Aerospace Engineering

Aerospace engineering is the discipline of engineering that is associated with the design, development, manufacture and testing of flight vehicles.

Telecommunications 

Telecommunications engineering, is the discipline of engineering that is associated with the design, development, manufacture and testing of communication systems concerned with the way information is sent and received. 

Chemical Engineering

Chemical Engineering is the discipline of engineering that is associated with the design, development, manufacture and testing of chemical products and chemical manufacturing processes. 

Civil Engineering

Civil engineering is the discipline of engineering that is associated with the design, development, manufacture and testing of infrastructures; bridges, roads, airports, and services (gas, electric, water, waste / drainage) 

Automotive Engineering

Automotive engineering is the discipline of engineering that is associated with the design, development, manufacture and testing of land based vehicles and transportation. 

Biomedical Engineering

Biomedical engineering, or Bioengineering, is the discipline of engineering that is associated with the design, development, manufacture and testing in the fields of biology and health care. Bioengineers work with doctors, therapists and researchers to develop systems, equipment and devices in order to address clinical problems.

Software Engineering

Software engineering is the discipline of engineering that is associated with the design, development, manufacture and testing of computer systems. It differs from other branches of engineering in that it looks at building systems which are intangible (something which cannot be touched).

Mechanical Engineering

Mechanical engineering is a discipline encompassing the application of principles from physics and mathematics to devise, construct, and analyze mechanical systems. These systems often employ mechanisms such as gears, pulleys, and hydraulics to achieve desired functions.

Gears, for instance, are mechanical components characterized by toothed wheels that interlock to transmit motion and power between rotating shafts. Pulleys, on the other hand, consist of grooved wheels over which belts or ropes are looped, facilitating the transmission of force and motion, particularly in lifting applications.

Hydraulics involve the utilization of fluids, typically oils or other liquids, to generate force or control motion within mechanical systems. By exploiting the incompressibility of fluids, hydraulic systems enable the precise manipulation of heavy loads or the smooth operation of machinery.

Mechanical engineers harness these fundamental mechanical elements, among others, to conceive, design, and optimize an array of devices and systems that serve diverse industrial, commercial, and societal needs.

Hydraulics work by transferring fluid pressure known as Pascal’s Principle. This can be understood easily by using a syringe full of liquid and a tube connected to another empty syringe. Hydraulics are used in a number of engineered products: 

- Breaking system on a car
- Lifting equipment; hydraulic jacks, wheelchair lifts
- Excavating arms on machinery such as diggers
- Hydraulic press machinery
- Wing flaps on aircraft

Gears are used for transmitting power from one part of a machine to another. In a bicycle, for example, it's gears, along with a chain, that take power from the pedals to the back wheel.

Using gears allows a mechanism to increase speed, increase force or change direction: To increase the speed you connect two gears, the first one should have more teeth, this means the second one has to turn round much faster. This means the second wheel turns faster than the first one but with less force. 

To increase the force the second wheel in a pair of gears has more teeth than the first one, it turns slower than the first one but with more force. To change direction two gears lock together, the second one always turns in the opposite direction. If the first one turns anticlockwise, the second one will turn clockwise. 

A pulley is used to change the direction of a force. By using a pulley you can pull down on the rope, taking advantage of the force of gravity, to lift the object up. This simple system can be enhanced by using several pulleys c together to further reduce the force needed to lift an object.

Pulleys are used in a number of engineered products:
- Lifts / elevators
- Cranes
- Washing machine
- Watches and clocks
