Joining processes for timbers

Design and technology

In this unit pupils will develop technical principles knowledge with an explicit focus on exam technique.

A ready-made part used across different products to make manufacturing easier is called a {{}}.

Which statement best defines a mechanical fixing?

adhesive works equally well on all materials

Which statement is correct about joining methods and materials?

driven in with a hammer; quick to use but not easily removed

threaded and turned into wood; creates a strong, removable joint

consists of two parts tightened together for strong, removable joins

used in flat-pack furniture; allows for disassembly and reassembly

Match the mechanical fixing to its correct description:

Use a countersink bit to create a recess for the screw head.

Insert and tighten the screw into the hole.

Check the screw head sits flush and the joint is secure.

Put the following steps in order for inserting a countersink head screw:

physical properties/characteristics relate to how a material looks and feels

working/mechanical properties describe material behaviour when exposed to forces

hardness is a physical property/characteristic

elasticity is a working/mechanical property

Which of the following statements is **incorrect**?

it can maintain its shape under normal conditions without breaking

it can resist environmental changes like temperature and moisture

the cost-effectiveness of building a structure

What does 'structural integrity' refer to in materials and structures?

they are always made from recycled materials

they're easier to transport, store, and use in different manufacturing processes

they don't require specialised tools to work with

What is one main benefit of using standard stock forms in manufacturing?

Shaping materials again without changing its basic chemical structure is called {{}}.

Which property would be **most** important when choosing a material for a flexible, stretchable item like a bungee cord?
