The drawer bottom is made from plywood.
Explain two advantages of making drawer bottoms from plywood rather than oak.
(4)
Two advantages explained from:
• Available in large sheets (1) which means planks
do not have to be glued together (1)
• Cheaper than solid oak (1) which means the
drawer will cost less (1)
• Plywood is less likely to warp / move than oak /
good dimensional stability / uniform strength (1)
which means the drawer will run smooth / will not
change shape (1)
• Plywood is more sustainable than oak (1) which
means we can preserve our natural timber supplies
(1)
• It is lighter than oak / it has a good strength to
weight ratio (1) which means it is easier to pull in
/ move (1)
The manufacturer of the drawers uses an EPOS system.
Give two pieces of information the manufacturer can store using an EPOS system.
Two pieces of information given from:
- Price / cost of item (1)
- Know what the item is (1)
- How many they have in stock (1)
- How many they have sold (1)
- Country of origin (1)
- When they were made (1)
- Material stock / information (1)
- Manufacturers details (1)
Describe two advantages, to the manufacturer of the desks, of using the internet to market
its business.
Two advantages described from:
• Reaches wide audience (1) quickly / cheaply (1)
• Can take orders online (1) and process
immediately (1)
• Regular e-mail contact with customers / suppliers
(1) to tell them about special offers / new
products (1)
• You can advertise (1) to increase sales/market
awareness (1)
• Search engines (1) can help direct customers to
their site / products (1)
• Cheaper than billboards / magazines (1) which
means they save money on advertising costs (1)
Give two properties of acrylic which make it suitable for the touch screen.
Two properties given from:
- stiffness (1)
- plasticity (1)
- durability (1)
- water resistant / water proof (1)
- clear / transparent / see through (1)
- lightweight (1)
(Do not accept tough / cuts shapes easily)
Explain why the torch is successful in meeting the following specification points:
(i) easy to switch on and off.
(ii) comfortable to carry.
(i)
One reason explained from:
• The large switch is in a position (1) which allows
the user to turn it on and off with their thumb /
easy to find in the dark (1)
• The switch is textured / shaped (1) which means
your thumb will not slip (1)
• The torch can be held and operated (1) with the
same hand (1)
(ii)
One reason explained from:
• A large handle is well positioned (1) therefore
making it balanced (1)
• The shaped handle (1) fits the shape of the users
hand (1)
• The textured / shaped handle (1) means it will not
slip / move in the hand (1)
The drawings below show two different types of torch.
Evaluate torch A compared with torch B.
Evaluation to address the following issues:
Torch A
- Once turned on it will stay on without having to power it
- Many component parts make it expensive to make
- Simple and easy to carry but it might be heavy due to the battery
- More expensive to run due to cost of batteries
- Batteries need to be disposed of so damage to environment
- Easier to hold the handle
- Easier for children to use with small hands
Torch B
- Continually needs powering / squeezing therefore you might get tired
- Does not use batteries therefore cheaper to run
- Lightweight because it has no batteries
- Complicated dynamo mechanism which could go wrong / snap / break easily
- No batteries to dispose of therefore better for the environment
- Squeezing the trigger constantly might cause it to slip in the hand
- Difficult for children to use / grip / squeeze
The drawing below shows a pair of scissors.
Give two properties of mild steel that makes it suitable for making the scissors.
For each property, justify your answer.
(4)
Two properties and linked justification from:
• Property: Tough (1)
• Justification: which means it can take knocks and
bumps / can be dropped without any damage (1)
• Property: Malleable (1)
• Justification which means it can be pressed into
shape without ripping / breaking
• Property: Good tensile / shear / compressive
strength (1)
• Justification which means it will withstand forces
being applied to it (1)
• Property: Hardness / can be hardened (1)
• Justification which means that it will not get
scratched easily / maintain a cutting edge / resist
indentation /wear (1)
(Do not accept strong / cheap / easy to work)
