2. Assessment Overview | 评估方式概览
Assessment consists of three components. Paper 1 is a 40-mark multiple-choice paper lasting 45 minutes, covering both Core and Extended content. Paper 2 is an 80-mark written theory paper with a duration of 1 hour 15 minutes. It includes short-answer and structured questions that test understanding of concepts and the ability to apply them.
评估由三个部分组成。试卷1是40分的选择题试卷，时长45分钟，涵盖核心和扩展内容。试卷2是80分的理论笔试试卷，时长1小时15分钟，包括简答题和结构题，考查对概念的理解及其应用能力。
The practical component is assessed either through Paper 3 (Practical Test) or Paper 4 (Alternative to Practical). Both are worth 60 marks and last approximately 2 hours 30 minutes. Students may be entered for the Core or Extended tier in Papers 1 and 2, allowing differentiated learning pathways.
实践部分可通过试卷3（实践考试）或试卷4（替代实践）进行评估。两者均为60分，时长约2小时30分钟。学生在试卷1和2中可以选择报考核心或扩展层级，以适应不同的学习路径。
In Year 10, teachers often focus on building core knowledge while introducing exam-style questions. Understanding the structure of each paper early helps students plan their revision and track progress against syllabus objectives.
在10年级，教师通常专注于构建核心知识，同时引入考试式问题。尽早了解每份试卷的结构有助于学生规划复习，并根据大纲目标跟踪进展。
3. Material Properties and Selection | 材料性质与选择
Engineers select materials based on a range of physical, mechanical, and thermal properties. Common categories include metals (steel, aluminium), polymers (PVC, nylon), ceramics, composites (carbon fibre reinforced plastic), wood, and smart materials like shape memory alloys. Each material group has distinct characteristics that suit different applications.
工程师根据一系列物理、机械和热学性质选择材料。常见类别包括金属（钢、铝）、聚合物（PVC、尼龙）、陶瓷、复合材料（碳纤维增强塑料）、木材以及形状记忆合金等智能材料。每类材料都有不同的特性，适合不同的应用。
Key properties to consider are density, stiffness (Young’s modulus), ultimate tensile strength, hardness, toughness, ductility, thermal conductivity, and electrical conductivity. For example, aluminium is chosen for aircraft structures because of its low density and good strength, while copper is used in wiring due to its excellent electrical conductivity.
需要考虑的关键性质有密度、刚度（杨氏模量）、极限抗拉强度、硬度、韧性、延展性、热导率和电导率。例如，铝因其低密度和良好的强度而被选用于飞机结构，而铜因其出色的导电性而用于电线。
Tensile testing is the standard method to obtain stress–strain data. Stress σ = F / A, where F is the applied force and A is the original cross‑sectional area. Strain ε = ΔL / L₀, the ratio of extension to original length. The initial linear portion of the graph gives Young’s modulus E = σ / ε. Hardness tests like Brinell and Rockwell measure resistance to indentation.
拉伸测试是获取应力–应变数据的标准方法。应力 σ = F / A，其中 F 是施加的力，A 是原始截面积。应变 ε = ΔL / L₀，即伸长量与原始长度的比值。曲线初始线性部分的斜率给出杨氏模量 E = σ / ε。布氏和洛氏等硬度测试则测量材料抵抗压痕的能力。
4. Manufacturing Processes | 制造过程
Manufacturing processes are grouped into casting, forming, machining, joining, and additive manufacturing. Casting involves pouring molten material into a mould (e.g. sand casting for large metal parts, die casting for precision). Forming processes such as forging, rolling, and bending reshape material without removing any, often improving mechanical properties.
制造过程可分为铸造、成形、机械加工、连接和增材制造。铸造涉及将熔融材料倒入模具（如大型金属部件的砂型铸造、精密零件的压铸）。成形工艺如锻造、轧制和弯曲在不移除材料的情况下重塑形状，通常还能改善机械性能。
Machining uses cutting tools to remove material. Turning on a lathe produces cylindrical shapes, milling creates flat surfaces and slots, and drilling makes holes. Joining techniques include welding (fusion of similar metals), brazing (using a filler metal above 450 °C for dissimilar metals), and adhesive bonding (for materials that cannot be heated).
机械加工使用切削工具去除材料。车床车削可加工圆柱形状，铣削可加工平面和槽，钻孔可加工孔眼。连接技术包括焊接（同类金属的熔合）、钎焊（使用高于450 °C的填充金属连接异种金属）和粘合剂粘接（用于无法加热的材料）。
Additive manufacturing, commonly called 3D printing, builds objects layer by layer directly from a CAD model. It allows rapid prototyping and complex geometries that would be difficult to produce by conventional methods. Each process has its own advantages, limitations, and typical materials used.
增材制造，俗称3D打印，可直接根据CAD模型逐层构建物体。它允许快速制作原型以及制造传统方法难以生产的复杂几何形状。每种工艺都有其自身的优点、局限性和常用材料。
5. Mechanics and Forces | 力学与力
A force is a vector quantity that can cause acceleration, deformation, or rotation. The moment of a force about a pivot is calculated as force × perpendicular distance. For an object to be in equilibrium, the sum of clockwise moments must equal the sum of anticlockwise moments, and the net force must be zero.
力是一个矢量，可引起加速度、变形或旋转。力对支点的力矩等于力乘以垂直距离。物体要处于平衡状态，顺时针力矩之和必须等于逆时针力矩之和，且合力必须为零。
When a material is loaded, internal stress σ = F / A and strain ε = ΔL / L₀ describe its response. Elastic deformation is reversible; once the load is removed, the material returns to its original shape. Plastic deformation is permanent. The yield point marks the transition.
当材料受载时，内部应力 σ = F / A 和应变 ε = ΔL / L₀ 描述了其响应。弹性变形是可逆的；一旦去除载荷，材料就恢复原状。塑性变形是永久性的。屈服点标志着这一转变。
Engineers use a factor of safety, defined as ultimate stress divided by working stress, to ensure structures perform reliably under expected loads. Simple beam bending theory explains how compression and tension are distributed across the cross-section.
工程师使用安全系数（极限应力除以工作应力）来确保结构在预期载荷下可靠工作。简单的梁弯曲理论解释了压应力和拉应力如何在横截面上分布。
6. Electronics and Control Systems | 电子学与控制系统
Basic electronic components include resistors, capacitors, diodes, and transistors. Ohm’s law V = I × R governs the relationship between voltage, current, and resistance. For series resistors, total resistance R_total = R₁ + R₂. For parallel resistors, the reciprocal rule applies: 1/R_total = 1/R₁ + 1/R₂.
基本电子元件包括电阻器、电容器、二极管和晶体管。欧姆定律 V = I × R 支配着电压、电流和电阻之间的关系。对于串联电阻，总电阻 R_total = R₁ + R₂。对于并联电阻，适用倒数规则：1/R_total = 1/R₁ + 1/R₂。
A potential divider is a simple circuit that produces an output voltage that is a fraction of the input. The output voltage V_out = V_in × (R₂ / (R₁ + R₂)), where R₂ is the resistor across which the output is taken. This is widely used with sensors such as thermistors and light-dependent resistors (LDRs).
分压器是一种简单电路，可输出输入电压的一部分。输出电压 V_out = V_in × (R₂ / (R₁ + R₂))，其中 R₂ 是输出端并联的电阻。这广泛应用于热敏电阻和光敏电阻 (LDR) 等传感器。
Systems are modelled as input–process–output blocks. Input transducers (sensors) convert physical signals into electrical ones; output transducers (actuators) perform actions such as lighting an LED or driving a motor. Microcontrollers like the PIC or Arduino can be programmed to process inputs and make decisions, enabling closed‑loop control with feedback.
系统按输入–处理–输出模块建模。输入换能器（传感器）将物理信号转换为电信号；输出换能器（执行器）执行点亮LED或驱动马达等动作。像PIC或Arduino这样的微控制器可编程处理输入并做出决策，实现带反馈的闭环控制。
7. Energy, Power and Efficiency | 能量、功率与效率
Mechanical work done = force × distance moved in the direction of the force. Power is the rate of doing work: P = work / time. For an object moving at constant velocity v under a constant force F, power can be expressed as P = F × v.
机械功 = 力 × 沿力方向移动的距离。功率是做功的速率：P = 功 / 时间。对于在恒力 F 下以恒定速度 v 运动的物体，功率可表示为 P = F × v。
Rotational power is given by P = torque × angular velocity. Efficiency is the ratio of useful output energy (or power) to total input energy. No system is 100% efficient due to friction and heat losses. Gear and belt drives are used to transmit power between shafts, with gear ratio determining the relationship between speed and torque.
旋转功率由 P = 扭矩 × 角速度 给出。效率是有用输出能量（或功率）与总输入能量之比。由于摩擦和热损失，任何系统都无法达到100%效率。齿轮和皮带传动用于在轴间传递动力，齿轮比决定了速度与扭矩之间的关系。
Understanding energy conversions is essential when analysing machines such as winches, pulleys, and electric motors. Students should be able to calculate efficiency from experimental data and explain why losses occur.
在分析绞车、滑轮和电动机等机器时，理解能量转换至关重要。学生应能根据实验数据计算效率，并解释为何会出现损失。
8. Engineering Drawing and Communication | 工程制图与沟通
Technical drawing is a universal language in engineering. Orthographic projection presents three 2D views—typically front, top, and side—arranged according to first or third angle conventions. Dimensions are added with extension and dimension lines, following standards such as BS 8888.
技术制图是工程学中的通用语言。正投影根据第一角或第三角投影法，呈现三个二维视图——通常是前视图、俯视图和侧视图。按照BS 8888等标准，使用延伸线和尺寸线添加尺寸标注。
Isometric drawing provides a 3D pictorial view where horizontal edges are drawn at 30° to the horizontal. This helps non‑engineers visualise the design. Students learn to read and produce both types of drawing, interpreting line weight, symbols, and title blocks.
等距图提供三维图形视图，其中水平边与水平线成30°角。这
