Engineering Types
What do Engineers do?
Solve problems
What is force?
Force is the push or pull affect that can CAUSE an object to move, stop, or change direction.
What is Kenetic Energy ?
The energy that comes from MOVEMENT.
What is Motion?
A change in an objects POSITION over TIME.
Why is it important for students to make sure they complete ONGUARD before using specialised equipment?
To make sure they can use the equipment safely.
Name TWO types of Engineering.
Aerospace, Bio-medical, Chemical, Civil, Computer Science, Electrical, Mechanical, Military, Robotics,
What are the TWO main categories that organise the different types of forces. (you must name both)
BONUS 200 - What is the difference between them?
Contact and Non-contact.
BONUS 200 - Contact forces need two or more objects to physically touch, and non-contact forces exist even when objects do not touch.
What is Potential Energy?
Energy that has been STORED, and has potential to be released.
What are three different types of motion?
Rectilinear (straight line), Rotational, Circular, Periodic
What is the purpose of a Design Folio?
To record the design process and collect any evidence needed for your class project.
What is engineering?
The use of MATHS, SCIENCE, and EVIDENCE to design and build an INNOVATIVE SOLUTION to a problem.
Magentism, Electro static, and Gravity are all examples of what?
Non-Contact Forces
What are the types of energy involved with making toast in a toaster?
Electrical Energy -- When the toaster is plugged in and switched on.
Thermal Energy -- The toaster generates heat to cook the bread in the toaster.
When a pendulum swings back and fourth, what kind of motion is occuring?
Periodic
What is meant by Evidence in Engineering?
Research, Testing, and Evaluation.
True or False, an Engineer's role is to observe the world around us and collect data, identifying properties of different objects, and more.
False. The role described is actually that of a SCIENTIST. An Engineer takes the data and uses it to create a solution to a problem.
Name three types of contact forces.
Applied force, Friction, Tension, Drag (or Air Resistance)
What are the two factors that determine how much Kinetic Energy something has?
Speed and Mass
(e.g., a huge comet travelling a high speeds toward earth has a lot more kinetic energy than a feather gently floating towards the ground.)
When a clock minute-hand moves at the start of a new minute, it begins by pointing at the 12, and as time passes, it point to each number until it points to the 12 again.
What types of motion occur?
Rotational - The hand rotates from the 12 around the clock, and back to the 12 again.
Periodic - The hand completes its movement over a 60 second period, and then continues to repeat the same motion at the start of every minute.
What is meant by Innovative Solutions in Engineering?
Forward thinking ideas, or thinking outside the box.
In ancient times, buildings were made with wood, stone, hay, clay and early variations of concrete. Today, buildings are made with very complex materials, starting with steel-fixing, formwork, metal foundations, wood frameworks and concrete outer shells, with wiring and electrical utilities and plumbing.
What type of engineering is this?
What aspect of this type has been explained?
CIVIL ENGINEERING.
The EVOLUTION of civil engineering (e.g., how civil engineering has changed over time).
What is the type of force that happens when an object is pulled in opposite directions?
BONUS 100 - What is an example of this force?
TENSION
BONUS 100 - When an elastic band is stretched, when muscles cramp, when clothes is too tight.
When car fuel burns in the engine, the energy starts off as:
- CHEMICAL POTENTIAL ENERGY and changes to
- THERMAL ENERGY when fuel burns, and changes to
- MECHANICAL ENERGY as the wheels spin.
What is this an example of?
Energy CONVERSION.
What happens in terms of motion with regards to the Earth and the Sun, during a single Earth-year.
The Earth takes a single trip in a CIRCULAR motion around the Sun.
In that single trip, the Earth rotates around its axis, giving us days and nights, spinning 365 times before it finishes its trip around the Sun.
What is meant by sustainable practice in any creative design project?
Environmentally friendly, waste reduction, and energy efficient.
