Welcome to the Year 8 OCR Engineering terminology quick guide! Engineering has its own language, and memorising key terms can feel like learning a new code. This guide breaks down essential vocabulary topic by topic, equipping you with memory tricks, acronyms, and visual associations to help you recall definitions quickly and accurately. Whether you are revising for an assessment or building a strong foundation, these techniques will turn tricky terms into lasting knowledge.

欢迎使用 Year 8 OCR 工程术语速记指南！工程学有自己的语言，记住关键术语就像是学习一种新的代码。本指南按主题分解核心词汇，为你配备记忆窍门、首字母缩略词和视觉联想，帮助你快速准确地回忆定义。无论你是为评估复习还是打下坚实基础，这些技巧都将把难记的术语转化为持久的记忆。

1. Engineering Materials & Properties | 工程材料与性能

Materials are the building blocks of every project. The following terms describe how materials behave under different conditions. A handy way to remember the main mechanical properties is the phrase “Tough Harry Dares Plastics” – Toughness, Hardness, Ductility, Plasticity. Let’s break them down.

材料是每个项目的基础构件。以下术语描述材料在不同条件下的表现。一个简便的方法来记住主要的机械性能是短语 “Tough Harry Dares Plastics” – 韧性、硬度、延展性、可塑性。我们来一一分解。

Here is a table of common material property terms and quick memory links:

Term (英文)	中文	Memory Trick
Tensile Strength	抗拉强度	Imagine a tense rope pulling – ‘tensile’ = tension.
Compressive Strength	抗压强度	Think of compacting rubbish – squeeze together.
Hardness	硬度	A hard material resists scratches – ‘hard’ like a diamond.
Ductility	延展性	Sounds like ‘duct’ – pipes are drawn out, like wires.
Malleability	可锻性	‘Mallet’ beats metal into thin sheets.
Elasticity	弹性	Like an elastic band – returns to original shape.
Plasticity	可塑性	Plasticine stays bent – permanent deformation.

这张表格汇总了常见的材料性能术语及记忆链接。例如，”抗拉强度” 与拉紧的绳子 (tension) 相关；”延展性” 让人联想到管道 (duct) 可以被拉成细丝。利用词根和形象画面，这些概念会变得牢固。

2. Manufacturing Processes | 制造工艺

From shaping wood to printing 3D objects, Year 8 introduces several processes. A mnemonic to order them from cutting to adding is “Charlie Dances To Music Inside Clouds” – Cutting, Drilling, Turning, Milling, Injection Moulding, Casting. Each process transforms raw material into a desired shape.

从木材成型到 3D 打印，八年级介绍了几种工艺。按从切割到添加的顺序记忆的口诀是 “Charlie Dances To Music Inside Clouds” —— 切割、钻孔、车削、铣削、注塑、铸造。每种工艺都将原材料转化为想要的形状。

Below is a quick reference table:

Process (英文)	中文	Memory Link
Cutting	切割	Saw or shearing action – think ‘cut’ like scissors.
Drilling	钻孔	Twist drill bit rotating – ‘Drill’ like a dentist.
Turning	车削	Workpiece turns on a lathe – ‘turning’ around.
Milling	铣削	Multi-tooth cutter rotates – ‘mill’ like a windmill.
Injection Moulding	注塑成型	Plastic injected into a mould – ‘injection’ like a syringe.
Casting	铸造	Molten metal poured into a mould – ‘cast’ like a movie cast formed.

上表提供了快速参考。”车削” 对应工件旋转，”注塑成型” 想象注射器把塑料注入模具。把这些形象画面记在脑中，工艺名称就自然浮现。

3. Forces, Loads & Stresses | 力、载荷与应力

Understanding how forces act on structures is crucial. Five key types of forces can be recalled with the sentence “Tiny Cats Try Stealing Biscuits” – Tension, Compression, Torsion, Shear, Bending. Each describes a different way a material can be loaded. Stress is the internal resistance to force, calculated by:

理解力如何作用在结构上至关重要。五种关键的力可以用句子 “Tiny Cats Try Stealing Biscuits” 来记忆——拉伸、压缩、扭转、剪切、弯曲。每一种都描述了材料承受载荷的不同方式。应力是材料内部抵抗力的量度，计算公式为：

Stress (σ) = Force (F) ÷ Area (A)

Here is a breakdown with examples:

Force	中文	Simple Image
Tension	拉伸	Pulling a rubber band – it gets longer.
Compression	压缩	Squashing a spring – it gets shorter.
Torsion	扭转	Twisting a wet cloth – ‘torsion’ = twist.
Shear	剪切	Scissors cutting paper – layers slide past each other.
Bending	弯曲	A diving board bending under weight.

这张分解表给每个力配了简单图像。”剪切” 就像剪刀剪纸——面层相互滑移。配合 σ = F ÷ A 公式，力与面积的关系便一目了然。

4. Mechanical Components | 机械部件

Gears, levers, and linkages are the language of movement. Use the phrase “Giant Leaping Puppies Chase Links” to remember: Gears, Levers, Pulleys
