Engineering
What is Green Engineering?
Green Engineering is the environmentally conscience attitudes, values, and principles combined with science and technology to improve local, regional and international principles
What is a pulley?
This simple machine consists of a wheel with a grooved rim around which a rope passes.
What is a volt?
This unit measures electric potential difference and electromotive force.
What is concrete?
This material, composed of cement, aggregate, and water, is widely used in construction.
"What is concrete?"
What are wings?
This part of an aircraft provides the majority of lift.
Suggest 2 principles of Green Engineering.
Inherent rather than circumstantial,
Prevention rather than treatment,
Design for separation,
Maximising efficiency,
Output pulled vs input pulled,
Conserve complexity,
Durability rather than immortality,
Meet needs and minimize excess,
Minimize material diversity,
Integrate material and energy flows,
Design for commercial afterlife,
Renewable rather than depleting.
What is Newton's Third Law of Motion?"
This principle states that for every action, there is an equal and opposite reaction.
What is a resistor?
This basic circuit component resists the flow of electric current.
What is an aqueduct?
This ancient Roman invention, crucial for transporting water over long distances, uses gravity to maintain a constant slope.
What is drag?
This force opposes an aircraft's motion through the air.
Define a resource.
A resource is anything that adds value to your life
What is the Carnot cycle?
This thermodynamic cycle, consisting of two isothermal and two adiabatic processes, describes the ideal heat engine.
What is a capacitor?
This device stores electric charge and consists of two conductors separated by an insulator.
What is a raft foundation?
This type of foundation distributes the load of a structure over a large area, typically used for softer soils.
What is stability?
This term describes the tendency of an aircraft to return to its original position after being disturbed.
Explain the Mathusian Theory by Thomas Maltus.
For every economic growth(such as overpopulation) there is a decline in quality of life such as famine and disease.
What is an internal combustion engine?
This type of engine, common in many cars, uses the up-and-down motion of pistons to create rotation.
What is a NOR gate?
This type of logic gate produces a high output only if all its inputs are low.
What is a truss bridge?
This type of bridge uses a series of triangular structures to spread the load.
What is the Brayton cycle?
This cycle, fundamental to jet engines, consists of compression, combustion, and expansion.
State the difference between intra and international equity.
The difference between intragenerational and intergenerational equity is that while they both stipulate the rights and obligations of generations, intragenerational equity focuses on the current generation(s) while intergenerational equity focuses on present and future generations
What is the Reynolds number?
This dimensionless number in fluid mechanics is used to predict flow patterns in different fluid flow situations.
What is Ohm's Law?
This law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
What is a triaxial test?
This geotechnical engineering test is used to determine the shear strength properties of soil.
What is the Bernoulli effect?
This effect, crucial in aircraft wing design, states that as the speed of a fluid increases, its pressure decreases.
