WHS & Risk Management
A student leaves a sharp blade on a desk. Is the blade a hazard or a risk?
Hazard
A designer interviews five students about their school bags. Is this primary or secondary research?
Primary
Which prototype is usually cheaper and quicker to make
Hint: (low-fidelity or high-fidelity)
Low-Fidelity
Is hardness a mechanical property or a thermal property?
Mechanical
Which type of intellectual property protects a company logo: patent, trademark or copyright?
Trademark
A workshop sign is a blue circle showing a person wearing safety glasses. Is it mandatory or a warning sign?
A designer uses a published government report about plastic waste. Is this primary or secondary research?
Secondary
A prototype uses the intended materials and a functioning mechanism. Is it low-fidelity or high-fidelity?
High-Fidelity
Is density a mechanical property or a physical/thermal property?
Physical/Thermal
Which P of innovation involves changing how a product is manufactured: product, process, position or paradigm?
Process
Which control comes first in the hierarchy: isolation or substitution?
Substitution
Which project tool uses horizontal bars to show tasks across a timeline?
Which drawing type shows separate front, side and top views?
Orthographic
In CFRP (Carbon Fibre Reinforced Polymer), which component provides the fibres: the reinforcement or the matrix?
Reinforcement
A designer tests whether different materials affect how long ice takes to melt. What is the independent variable?
Material Type
A machine produces harmful fumes. Which is higher in the hierarchy: installing local exhaust ventilation or providing a mask?
Installing local exhaust ventilation (control)
A competitor opens a new shop nearby. In a SWOT analysis, is this a strength, weakness, opportunity or threat?
Threat
A component must measure between 49 mm and 51 mm. A manufactured part measures 48 mm. Is it within tolerance?
No
A factory must produce 100,000 identical plastic parts. Which process generally has the lower cost per part: injection moulding or 3D printing?
Injection Moulding
In the same experiment, what is the dependent variable if the designer measures the time taken for the ice to melt?
Time taken for the ice to melt
Put these controls in order from most to least effective: PPE, elimination, administrative controls, engineering controls, substitution, isolation.
Elimination → Substitution → Isolation → Engineering → Administration → PPE
A designer discovers that their product costs too much to manufacture. In a SWOT analysis, is this a strength, weakness, opportunity or threat?
Weakness
A 3D object has a width of 40 mm, a height of 30 mm and a length of 60 mm. In an orthographic drawing, how wide is its front view if the front shows length and height?
60mm wide and 30mm high
A metal component returns to its trained shape when heated. Which material category does it belong to: composite, smart material or thermoplastic?
Smart Material
A designer tests three materials using identical-sized blocks, equal starting temperatures and the same room conditions. Name the variable deliberately changed and two variables kept constant.
Independent variable: material type. Control variables: block size and starting temperature (room conditions is also correct).
