What does a scale of 1:2 mean?
For every 1cm on the page, it represents 2cm in real life
Rolling, Folding and Tubing are all examples of what?
Methods of Reinforcing
Why are levers important?
They help us to do a lot of work with little effort

Three (3)
List the 6 steps of the EDP:
Ask, Imagine, Plan, Create, Improve, Communicate
List and explain the 3 types of line.
Outlines; dark continuous lines. Construction lines; feint lines used to help construct other lines. Hidden Detail lines; dashed lines used to show parts we can't see.
The 3 types of structures are?
Shell, Solid, Frame

List 4 Design Considerations:
(Any 4) Is it safe? Is it ergonomic? Is it aesthetic? Is it cost effective? What is it for? Who is it for? Is it cost effective? Will it do the job? How does it impact people/society/the environment?
What angle are the lines on the following drawings drawn at? A) Isometric Drawings, B) Oblique Drawings
Isometric Drawings are drawn at 30* and Oblique Drawings are drawn at 45*
List the 4 main functions of Structures:
Protect, Support, Contain, Span
What are the 3 examples of linkages that we wrote about in our books?

Explain in detail how the amount of rope needed changes when we add more pulley to a system
[Check with Miss Fish]
Explain, with examples, what knowledge, skills and resources are.
Knowledge; things that I know. (Own example) Skills; things that I can do. (Own example) Resources; things that I can use. (Own example)
Explain the difference between dimensions and scale in detail
Dimension is adding measurement to a drawing, the height, width and depth are shown to give a more accurate depiction. Scale is a sizing up or sizing down of an object to make it easier and more practical to draw.
List the 5 types of forces we learnt about in Term 2
Compression, Tension, Torsion, Shearing, Bending
Which class of lever provides the greatest mechanical advantage; first, second or third? Explain
Neither, they all serve different purposes for what they are used for. It is how the lever is built that determines the amount of mechanical advantage.
Aside from a lever and a pulley, the remaining 5 simple mechanisms are
Crank, Incline Plane, Wedge, Screw, Wheel and Axle
