5. Mechanical Systems and Components | 机械系统与组件
Simple mechanisms change the magnitude or direction of force and motion. Levers (class 1, 2, 3) use a pivot, effort, and load. Mechanical advantage (MA) is calculated as load ÷ effort.
简单机构可以改变力和运动的大小或方向。杠杆（一类、二类、三类）利用支点、动力和负载。机械效益 (MA) 计算为 负载 ÷ 动力。
Gear trains transmit rotary motion. The velocity ratio depends on the number of teeth. A small driver gear turning a large driven gear increases torque but reduces speed. Use the formula:
齿轮系传递旋转运动。传动比取决于齿数。小驱动齿轮带动大从动齿轮可增加扭矩但降低速度。使用公式：
Velocity Ratio = Teeth on driven gear ÷ Teeth on driver gear
传动比 = 从动轮齿数 ÷ 主动轮齿数
Pulleys and belts work similarly; the ratio relies on pulley diameters. Cams and followers convert rotary motion into reciprocating motion. Know how to sketch and label these systems for the exam.
带轮和皮带工作原理类似；传动比取决于带轮直径。凸轮和从动件将旋转运动转化为往复运动。应懂得如何为这些系统画草图并标注，以应对考试。

对于电子电路，万用表测量电压、电流和电阻。示波器可显示信号波形。你将学习收集数据并以表格和图表呈现结果，将测试结果与 PDS 标准进行对比。
Prototyping and testing often reveal weaknesses. You should suggest modifications, e.g. adding ribs to strengthen a plastic casing, and explain how the change improves performance—a skill directly assessed in the NEA.
原型制作和测试常会暴露弱点。你应提出修改方案，例如增加加强筋来强化塑料外壳，并解释这一改动如何提升性能——这正是 NEA 直接考查的技能。
11. Preparing for the NEA (Non-Exam Assessment) | 非考试评估 (NEA) 准备
In Year 10, you will undertake mini-projects that mirror the NEA process: responding to a design context, analysing user needs, writing a PDS, and generating a range of ideas. This practice builds confidence for the real assignment in Year 11.
在十年级，你将进行模拟 NEA 流程的微型项目：回应设计背景、分析用户需求、撰写 PDS 并产生一系列创意。这一练习能为十一年级的正式任务建立信心。
The NEA portfolio requires evidence of research (including disassembly of existing products), considered material/component choices, manufacturing plans with step-by-step stages, and a thorough evaluation against the specification. Use photographs and annotated sketches to communicate your thinking.
NEA 作品集需要研究证据（包括拆解现有产品）、经过考量的材料/元件选择、带有分步阶段的制造计划以及针对规格的全面评估。用照片和注解草图传达你的思路。
Time management is critical. Break the project into phases—design, make, evaluate—and set milestones. Revision guides and past NEA exemplars (often provided by your teacher) can show exactly what the examiner looks for.
时间管理至关重要。将项目分阶段进行——设计、制造、评估——并设定里程碑。复习指南和往年 NEA 范例（通常由老师提供）可以清晰展示考官的要求。
12. Revision Tips and Resources | 复习技巧与资源
