An electric motor is an electrical machine that converts electrical energy into mechanical
energy.
A device for making and breaking the
connection in an electric circuit

The pillar drill is used for accurately drilling holes through materials including a range of woods, plastics and metals. Which of the following is NOT used for a pillar drill?
Tap Wrench
HSS twist drill bit
Holesaw
Spade bit
Chuck key – Used for tightening the chuck, the spring makes sure the key cannot accidentally be left in the chuck causing injury.
True
False
Computer Aided Design - CAD
(Choose 2)
CAD uses design software such as 2D Design, Fusion 360 or Sketchup. It allows the designer to draw a product in detail.
CAD is the manufacturing of a product on a machine such as a laser cutter or 3D Printer.
Products can be designed and modified quickly using CAD, allowing the testing of prototypes during the design process, without the need to make it.
CAD is a slow drawing process that is difficult to correct errors.
To cut an internal thread, you would use a:
Tap
Die
An example of a thread measurement is: M10 x 1.5.
M10 means what?
Metric diameter of the thread (10mm).
Metric radius of the thread (10mm).
The distance between the threads.
You are driving down Motorway 10.
Which of the following is NOT an example of PPE (Personal Protective Equipment)?
Goggles
Heat proof gloves
Beats Headphones
Face mask
Shoes with toe protection
The ability of a material to withstand a force without breaking or bending:
Tensile Strength
Elasticity
Malleability
Ductility
The ability of a material to bend and then to return to its original shape and size is called:
Corrosive Resistance
Elasticity
Malleability
Toughness
The ability of a material to be shaped without breaking is:
Malleability
Durable
Elasticity
Conductivity
What needs to be considered when developing an environmentally friendly design? (Choose 4)
;)
How will the use of the product affect the environment?
How will you dispose of the product when it reaches it's useful lifespan?
Can the product be made from recycled materials?
Is the product able to be maintained/sustained?
Materials are tested in which of the following ways... (choose 4)
Tension: Forces pulling in opposite directions.
Compression: Forces that are trying to crush or shorten.
Bending (Flexing) and Torsion (Twisting)
Squishablity: hugging an object to see how much it can be scrunched.
Shear: A strain produced when an object is subjected to opposing forces.
To calculate the area of a rectangle:
LxW
π r2
2D Engineering drawings are called:
Orthographic
Isometric
A section view on an engineering drawing shows:
an area or hidden part of an object by cutting away or removing some of that object.
dotted lines to show hidden details of threads.
the front, plan and side view.
