Question 1

SLPaper 1

Which manufacturing technique involves clamping a thermoplastic sheet over a mould, heating it until it is pliable, and then removing the air from the cavity to shape the material?

Compression moulding

Vacuum forming

Injection moulding

Rotational moulding

Question 2

SLPaper 1

A manufacturer is developing a casing for a heavy-duty electrical component. They require a polymer that will not soften or change shape once it has been cured, even if subjected to extreme heat during a circuit failure.

Which characteristic of the polymer's molecular structure provides this specific property?

The presence of weak secondary bonds between linear molecules

The formation of extensive covalent cross-links during setting

The use of large side groups to prevent chain sliding

The alignment of molecular chains into highly crystalline regions

Question 3

SLPaper 1

The table below lists the characteristics of four different smart materials.

Material	Triggering Stimulus	Observed Response
W	UV radiation	Reversible change in colour
X	Mechanical stress	Generation of a small electric voltage
Y	Thermal energy	Reversion to a pre-programmed shape
Z	Physical pressure	Significant drop in electrical resistance

Which material in the table displays the properties of a Shape Memory Alloy (SMA)?

Material W

Material X

Material Y

Material Z

Question 4

SLPaper 1

Which of the following is a heat treating process?

Warping

Seasoning

Tempering

Felting

Question 5

SLPaper 1

Which characteristic of Medium Density Fibreboard (MDF) makes it a preferred choice for creating decorative furniture panels with intricate routed details?

It is significantly lighter and easier to handle than other manufactured boards.

It is composed of thin wood veneers bonded at 90-degree angles to one another.

It has a uniform, grain-free structure that allows for clean machining in any direction.

It contains high levels of natural resin that make it waterproof without additional finishing.
