what is mechanical engineering?
Mechanical engineering is a branch of engineering which combines engineering physics and mathematics with materials science.
This helps to design, analyse, manufacture, and maintain mechanical systems.
briefly list some tasks a mechanical engineer would do
Mechanics.
Mechatronics and robotics.
Structural analysis.
Thermodynamics and thermo-science.
Design and drafting.
what are gears?
Gears are a toothed wheel that works with another wheel to change the speed of a driving mechanism (for example, the engine of a vehicle) and the speed of the driven parts.
what are pulleys?
Pulleys are a wheel with a grooved rim that allows a rope to pass through, this acts to change the direction of a force applied to the rope and is used to lift heavy weights.
what are hydraulics?
Hydraulics is a mechanical function that operates by introducing pressure to a liquid.
In hydraulics systems, mechanical movement is produced by, pumping liquid (oil), usually through hydraulic cylinders to move pistons.
what is electrical engineering?
Electrical engineering is a discipline that studies the design, and application of equipment, devices, and systems that use electricity, electronics, and electromagnetism.
briefly name some tasks an electrical engineer would carry out
Computer.
Systems.
Power.
Telecommunications.
Radio.
Signal.
Instrumentation.
Electronic.
Optics.
describe the differences between AC and DC in electrical engineering
AC refers to alternating current, Alternating Current (AC) is a type of electrical current, in which the direction of the flow of the electrons changes back and forth at regular intervals.
DC refers to direct current, which means the current only flows in one direction.
what type of current do power stations use and why?
Power stations generate AC current and not DC. This is because the transmission of alternating current is easier and very efficient. The transformers in the power station can step up and step down the voltage of the alternating current.
name some examples of household appliances that use DC
Mobile phones.
Laptops.
Microwaves.
Batteries.
Lamps.
Name some household appliances that use AC
Fridges.
Televisions.
Radio signals fans
what is electronical engineering and why does it differ to electrical engineering?
Electronics engineering is a sub-discipline of electrical engineering this began to be performed in the early 20th century.
It is different to electrical engineering by the extra use of components such as semiconductor devices to amplify and control electric current flow
what is an integrated circuit (electronic engineering)?
An integrated circuit (IC), also called a chip or microchip, is a semi-conductor wafer on which thousands or millions of tiny resistors, capacitors and transistors are fabricated.
what is a PCB (electronic engineering)?
A printed circuit board (PCB) is used for physically supporting and wiring the surface-mounted and socketed components in most electronics.
They are used to mechanically support and electrically connect electronic components which use conductive pathways or tracks which are etched from copper sheets laminated onto a non-conductive substrate.
what is a transmitter(electronic engineering)?
A transmitter is an electronic device used to produce radio waves to transmit or send data with the aid of an antenna.
The transmitter can generate an AC frequency that is then applied to the antenna, which, in turn, radiates this as radio waves.
Laptop, wireless microphone, mobile, wireless headset, wireless internet router.
what are input/output receivers?(electronic engineering)
Receivers gather useful data and information in the air.
Production of radio waves with the help of the antenna provided generates radio frequency on, this is the signal receivers get to create for example sound.
what is aerospace engineering?
Aerospace engineering is the main field of engineering which is concerned with the development of aircraft and spacecraft.
There are two major branches:
Aeronautical engineering.
Astronautical engineering
What are the fields of aeronautical engineering?
The fields of aeronautical engineering include:
* Thermodynamics
* Propulsion systems
* Fluid dynamics
* Electronics
* Navigation
* Structural and mechanical design
These fields focus on various aspects of aircraft design and operation.
What is the difference between aerospace and aeronautical engineering?
Aerospace engineering encompasses both aeronautical and astronautical engineering, while aeronautical engineering specifically deals with aircraft.
What is spacecraft engineering?
Spacecraft engineering is a different sector from aerospace engineering, focusing on the design and operation of spacecraft.
What are some specialized areas in the spacecraft industry?
Specialized areas in the spacecraft industry include:
* Rocket propulsion
* Orbital mechanics
* Spacecraft design
* Human life-support in space
* Space environments
* Mission design and systems engineering
These areas are critical for the successful operation of spacecraft.
How are aerospace engineers involved in military projects?
Aerospace engineers help design and create missiles and missile systems used by various military organizations.
What event marked the significant development of the aerospace industry?
The aerospace industry significantly developed with Wilbur and Orville Wright’s first flight in 1903.
What is aerospace engineering?
Aerospace engineering is the main field of engineering concerned with the development of aircraft and spacecraft.
