3. Understanding the Engineering Design Process | 理解工程设计流程
The engineering design process is a systematic cycle used to develop solutions to problems. It begins with defining the problem clearly and establishing design criteria and constraints, such as cost, size, weight, and safety regulations. You then research existing products, generate creative ideas through brainstorming, and select the most promising concept to develop further.
工程设计流程是一个系统的循环，用于开发问题的解决方案。它始于清晰地定义问题，并制定设计标准和约束条件，如成本、尺寸、重量和安全法规。然后你研究现有产品，通过头脑风暴产生创意，并选择最有前景的方案进行进一步开发。
Prototyping is a crucial step – it allows you to test and evaluate your design against the criteria, identify weaknesses, and make improvements. This iterative loop of testing and redesigning is at the heart of engineering: 'fail early to succeed sooner'. Engineers document every stage to ensure the final product is safe, efficient, and fit for purpose.
原型制作是关键步骤——它让你能够根据标准测试和评估设计，发现弱点并进行改进。这种测试和重新设计的迭代循环是工程的核心：“尽早失败，更快成功”。工程师记录每个阶段，以确保最终产品安全、高效且符合用途。
4. Materials and Their Properties | 材料及其特性
Selecting the right material is one of the most important decisions in engineering. Materials are grouped into families: ferrous metals (containing iron, e.g. mild steel, cast iron), non-ferrous metals (aluminium, copper), polymers (acrylic, nylon, ABS), ceramics, and composites (carbon fibre, glass-reinforced plastic). Each has unique properties that make it suitable for specific applications.
选择合适的材料是工程中最重要的决策之一。材料分为不同类别：黑色金属（含铁，如低碳钢、铸铁）、有色金属（铝、铜）、聚合物（丙烯酸、尼龙、ABS）、陶瓷和复合材料（碳纤维、玻璃增强塑料）。每种材料都具有独特的特性，使其适用于特定的应用场景。
Engineers consider tensile strength, hardness, toughness, ductility, electrical and thermal conductivity, density, and corrosion resistance. A table summarising common materials and their key properties is shown below:
工程师会考虑抗拉强度、硬度、韧性、延展性、导电导热性、密度和耐腐蚀性。下表总结了常见材料及其关键特性：
| Material | Key Properties | Example Uses |
| Mild Steel | High tensile strength, ductile, magnetic, corrodes | Car bodies, beams, bolts |
| Aluminium | Lightweight, corrosion-resistant, good conductor | Aircraft frames, cans, heat sinks |
| Acrylic | Transparent, brittle, easy to thermoform | Displays, windows, signs |
| Carbon Fibre | Very strong, very stiff, lightweight, expensive | Racing bikes, aerospace components |
5. Manufacturing Processes & Techniques | 制造工艺与技术
Understanding manufacturing processes helps engineers choose how to turn a design into a physical product. Traditional methods include cutting (sawing, drilling, laser cutting), forming (bending, casting, forging), and joining (welding, soldering, adhesive bonding). Surface finishing techniques such as painting, polishing, and anodising enhance appearance and durability.
理解制造工艺有助于工程师选择如何将设计转化为实物产品。传统方法包括切割（锯切、钻孔、激光切割）、成形（弯曲、铸造、锻造）和连接（焊接、锡焊、粘合）。表面处理技术如喷漆、抛光和阳极氧化，可以提升外观和耐用性。
Modern manufacturing increasingly relies on computer numerical control (CNC) machines, which follow digital models to cut or shape materials with high precision. Additive manufacturing (3D printing) builds objects layer by layer, allowing complex geometries that are impossible with subtractive methods. As a Year 10 student, you'll gain hands-on experience with basic workshop tools and possibly an introduction to CAD/CAM integration.
现代制造越来越依赖计算机数控（CNC）机床，它们按照数字模型高精度地切割或成型材料。增材制造（3D打印）逐层构建物体，能够实现减材方法无法实现的复杂几何形状。作为十年级学生，你将亲身体验基本车间工具，并可能初步接触CAD/CAM集成。
6. Mechanical Systems and Structures | 机械系统与结构
Mechanical systems transmit and control forces and motion. You will study simple machines such as levers, linkages, pulleys, and gears. The principle of moments explains how a force applied at a distance from a pivot creates a turning effect.
机械系统传递和控制力和运动。你将学习杠杆、连杆机构、滑轮和齿轮等简单机械。力矩原理解释了距离支点一定距离处施加的力如何产生转动效应。
The moment of a force is calculated as:
力的力矩计算公式为：
M = F × d
he force in newtons (N), and d is the perpendicular distance from the pivot in metres (m). vantage (MA) measures how much a mechanism multiplies the input force: MA = Load ÷ Effort.
其中 M 为力矩，单位牛顿米（Nm）；F 为力，单位牛顿（N）；d 为到支点的垂直距离，单位米（m）。机械效益（MA）衡量机构将输入力放大了多少倍：MA = 负载 ÷ 作用力。
on driven gear ÷ Number of teeth on driver gear. Understanding these relationships is essential for designing moving parts and ensuring structural stability.
齿轮可以改变转速、扭矩和旋转方向。简单的齿轮比可以通过比较齿数求得：齿轮比 = 从动齿轮齿数 ÷ 主动齿轮齿数。理解这些关系对于设计运动部件和确保结构稳定性至关重要。
7. Engineering Mathematics & Calculations | 工程数学与计算
Mathematical skills are the foundation of every engineering discipline. You will regularly calculate areas, volumes, densities, forces, stresses, and energy transfers. Being comfortable with unit conversions (e.g. mm² to m², g/cm³ to kg/m³) is essential.

Stress (σ) measures how hard a material is being pulled or compressed internally, and strain (ε) measures how much it deforms relative to its original size.
应力（σ）衡量材料内部受拉或受压的强度，应变（ε）衡量材料相对于原始尺寸的变形程度。
σ = F ÷ A
ε = ΔL ÷ L₀
ross-sectional area (m²), ΔL is the change in length, and L₀ is the original length. Young's modulus E = σ ÷ ε describes a material' V and calculate efficiency: Efficiency = (Useful energy output ÷ Total energy input) × 100%.
F 为施加的力（N），A 为横截面积（m²），ΔL 为长度变化量，L₀ 为原始长度。杨氏模量 E = σ ÷ ε 描述了材料的刚度。你还会应用密度方程 ρ = m ÷ V，并计算效率：效率 = （有用能量输出 ÷ 总能量输入）× 100%。
8. Reading Engineering Drawings & CAD | 阅读工程图纸与CAD
Engineering drawings are the universal language of manufacturing. You will learn to interpret orthographic projections (typically third-angle projection in the UK), sectional views, and dimensioning rules. Title blocks contain vital information such as scale, material, and tolerances.
