Exploring Engineering Design Principles

What is the primary focus of user-centred design?

• The aesthetics of the product

• The needs and preferences of the user

• The cost of production

• The speed of manufacturing

Which of the following is a common modelling method used in engineering design?

• Watercolour painting

• Finite Element Analysis (FEA)

• Origami

• Calligraphy

What is the main advantage of injection moulding in manufacturing?

• It is suitable for small-scale production

• It allows for high-volume production with consistent quality

• It is the cheapest method for all types of materials

• It requires no initial setup cost

Which material is commonly used in 3D printing?

• Wood

• PLA (Polylactic Acid)

• Glass

• Steel

What is a key benefit of using 3D sketching techniques in design?

• It eliminates the need for prototypes

• It allows designers to visualise complex shapes easily

• It is faster than digital modelling

• It requires no training

In user-centred design, what is the purpose of creating personas?

• To develop fictional characters for marketing

• To represent different user types and their needs

• To design the product's packaging

• To determine the product's price

Which of the following is a limitation of injection moulding?

• It is not suitable for mass production

• It has high initial setup costs

• It cannot produce complex shapes

• It is only suitable for metal products

What is the typical layer thickness in 3D printing using FDM technology?

• 0.1 to 0.3 millimetres

• 1 to 3 centimetres

• 10 to 30 metres

• 1 to 3 inches

Which of the following is a common tool used in 3D sketching?

• Paintbrush

• Stylus and tablet

• Hammer

• Ruler

What is a common challenge when using 3D printing for manufacturing?

• Limited material options

• Excessive waste production

• Inability to create prototypes

• High cost of raw materials
