3. Mechanical Systems and Forces | 机械系统与力
Mechanical systems form the backbone of many engineering applications. You need to be comfortable with basic force analysis, moments, and equilibrium. The relationship between force, mass, and acceleration is central to dynamics.
机械系统是许多工程应用的基础。你需要熟练掌握基础的力的分析、力矩和平衡。力、质量和加速度之间的关系是动力学的核心。
F = m × a
Consider a trolley being pulled along a bench: if the unbalanced force is 12 N and the mass is 4 kg, the acceleration will be 3 m/s². Understanding how to resolve forces into perpendicular components is also key when analysing structures like bridges or trusses.
设想一辆沿实验台移动的小车：如果非平衡力为 12 N，质量为 4 kg，那么加速度就是 3 m/s²。在分析桥梁或桁架等结构时，理解如何将力分解为垂向分量也至关重要。
Familiarise yourself with the principle of moments and the equation for calculating torque. A simple see-saw scenario can help you visualise how clockwise and anticlockwise moments must balance for a system to be in equilibrium.

V = I × R
If a resistor of 220 Ω has a current of 0.05 A flowing through it, the voltage across it is 11 V. Being able to calculate total resistance in series and parallel circuits is equally important. Summer practice can involve using a multimeter to measure continuity and resistance on simple breadboard circuits.
如果一个 220 Ω 的电阻流过 0.05 A 的电流，那么其两端电压是 11 V。能够计算串联与并联电路的总电阻同样重要。暑期练习可以包括使用万用表在简单的面包板电路上测量通断与电阻。
You will also be introduced to semiconductors, such as diodes and transistors, and how they are used in switching and amplification. Understanding input and output transducer subsystems — including LDRs, thermistors, LEDs, and buzzers — is essential for designing sensor-controlled systems.
你还将接触半导体，如二极管和晶体管，以及它们如何在开关和放大中应用。理解包含光敏电阻、热敏电阻、LED 和蜂鸣器等器件的输入输出换能器子系统，对于设计传感器控制系统至关重要。

7. Energy, Power and Efficiency | 能量、功率与效率
Energy conservation is a core engineering principle. You will calculate kinetic energy, gravitational potential energy, work done, and power in mechanical systems, as well as quantify electrical power using P = V × I or P = E / t.
能量守恒是一个核心工程原理。你将计算机械系统中的动能、重力势能、做功和功率，并使用 P = V × I 或 P = E / t 量化电功率。
Eₚ = mgh Eₖ = ½mv²
Efficiency measures how well a system converts input energy into useful output. An electric motor lifting a weight may receive 100 J of electrical energy but only do 80 J of useful work; the efficiency is 80%. The remaining energy is dissipated as heat or sound.
效率衡量系统将输入能量转化为有用输出能量的程度。一个电动机提升重物可能接收 100 J 电能，却只做了 80 J 的有用功，则效率为 80%。其余能量以热或声的形式耗散。
Understanding Sankey diagrams and energy audits will strengthen your ability to evaluate and improve system designs. You can practise by analysing energy transformations in household devices and looking for ways to minimise waste.

8. Pneumatics and Hydraulics | 气动与液压系统
Fluid power systems use compressed air or pressurised liquid to produce movement and force. In pneumatics, you will encounter single-acting and double-acting cylinders, directional control valves, and logic valves that mirror electronic functions.
流体动力系统利用压缩空气或加压液体来产生运动和力。在气动系统中，你会接触到单作用气缸、双作用气缸、方向控制阀以及能够实现类似电子功能的气动逻辑阀。
A basic circuit might use a push-button valve to extend a cylinder and a return spring to retract it. Being able to draw and interpret pneumatic circuit diagrams according to standard symbols is a tested skill, so begin familiarising yourself with these symbols early.
一个基础的回路可能使用按钮阀使气缸伸出，并通过复位弹簧使其缩回。能够按照标准符号绘制和解读气动回路图是一项考试考查的技能，因此要尽早开始熟悉这些符号。
Hydraulic systems rely on the incompressibility of liquids to transmit large forces. The relationship between force, area, and pressure — P = F / A — underpins braking systems and heavy lifting equipment. The summer is a great time to observe these systems in construction machinery or car braking mechanisms.
液压系统依赖液体的不可压缩性传递巨大作用力。力、面积与压力的关系—— P = F / A ——是制动系统和重型起重设备的基础。暑期是观察工程机械或汽车制动机构中这些系统的绝佳时机。
