COMPREHENSIVE EXAM SCRIPT
⩥ Define the following material properties:
- malleability
- elasticity
[2 marks]. Answer: One mark per correct definition of the material
properties.
• Malleability: A material's ability to be permanently deformed or shaped
by impact, rolling or pressing without cracking.
• Elasticity: A material's ability to be deformed and return to its original
when the force is removed.
⩥ State three ways that manufacturers are improving sustainability
throughout product manufacture. [3 marks]. Answer: 1 mark per relevant
point. Indicative content:
,Sustainability can be improved by reducing:
• the number of manufacturing processes used
• the volume or quantity of raw materials used
• the use of finite materials by choosing a more environmentally friendly
alternative
• the use of toxic materials or materials that can be damaging or harmful
to the environment
• the use of finishes that may be harmful to the environment
• the amount of energy used in factories or manufacturing facilities by
installing low energy lighting etc.
• the amount of energy used that is generated from finite resources by
seeking alternative sustainable sources.
⩥ Explain why high speed steel would be a suitable material for a metal
drill bit. [6 marks]. Answer: Indicative content:
, • HSS is an extremely hard material that resists abrasion and wear,
maintaining a sharp cutting edge on the drill bit.
• HSS is capable of withstanding the high temperatures caused by the
friction of cutting, without losing its hardness.
• Its resistance to wear allows it to drill other metals at high speeds.
• HSS is an alloy containing chromium that is highly resistant to
corrosion allowing HSS drill bits to be used with a variety of lubricants
and cutting compounds.
• HSS can be coated to improve its performance. A titanium nitride
coating can be used to further reduce friction and improve performance.
⩥ Describe the main stages in the process of soft soldering. [6 marks].
Answer: Indicative content:
• The components should be clean and free from grease or impurities.
• Flux may be used to help the solder flow and prevent oxidisation when
heating. The flux can be added separately or may be present in the core
of the solder itself.
