3. Material Properties and Testing | 材料性能与测试

Key mechanical properties include tensile strength, compressive strength, hardness, toughness, ductility, and elasticity. These are often evaluated through standardised tests.

关键力学性能包括抗拉强度、抗压强度、硬度、韧性、延展性和弹性。这些性能通常通过标准化测试进行评估。

In a tensile test, a specimen is stretched until fracture; the resulting stress‑strain graph reveals the elastic limit, yield point, and ultimate tensile strength.

在拉伸试验中，试件被拉伸至断裂；得到的应力‑应变曲线可以显示弹性极限、屈服点和极限抗拉强度。

σ = F / A₀

Engineering stress σ is the applied force F divided by the original cross‑sectional area A₀.

工程应力 σ 等于施加的力 F 除以原始横截面积 A₀。

Hardness can be measured using the Brinell or Rockwell methods, while impact resistance is assessed via Izod or Charpy tests. Non‑destructive testing (NDT) methods such as dye‑penetrant and ultrasonic inspection are also covered.

硬度可通过布氏或洛氏方法测量，抗冲击性通过悬臂梁或夏比测试评估。课程还涵盖染料渗透和超声波检测等无损检测 (NDT) 方法。

6. Mechanical Systems and Mechanisms | 机械系统与机构

The syllabus covers the principles of forces, motion, and energy transfer in simple machines. Calculations involving mechanical advantage, velocity ratio, and efficiency are frequently examined.

大纲涵盖简单机器中的力、运动和能量传递原理。涉及机械效益、速度比和效率的计算常出现在考试中。

For a simple lever:

对于简单杠杆：

Mechanical Advantage (MA) = Load / Effort

Velocity ratio (VR) depends on the geometry; efficiency η is the ratio of output work to input work, often expressed as a percentage:

速度比 (VR) 取决于几何尺寸；效率 η 是输出功与输入功之比，通常以百分比表示：

η = (MA / VR) × 100%

Gear trains, belt drives, chain drives, and linkages are analysed for torque, speed, and direction changes. For example, in a compound gear train, the overall gear ratio is the product of the individual ratios.

齿轮系、带传动、链传动和连杆机构需分析其扭矩、转速和方向变化。例如，在复式齿轮系中，总齿轮比为各级齿轮比之积。

Moments and equilibrium calculations are essential for structural analysis: for a component in static equilibrium, the sum of clockwise moments equals the sum of anticlockwise moments.

力矩和平衡计算对结构分析至关重要：对于处于静力平衡的构件，顺时针力矩之和等于逆时针力矩之和。

P = I × V

Students must be able to calculate total resistance for series and parallel circuits:

学生必须能够计算串联和并联电路的总电阻：

Series: Rₜₒₜₐₗ = R₁ + R₂ + R₃ …

Parallel: 1/Rₜₒₜₐₗ = 1/R₁ + 1/R₂ + 1/R₃ …

Sensing circuits often incorporate thermistors and light‑dependent resistors (LDRs) as part of a potential divider. Output devices include LEDs, buzzers, and relays. Transistors can be used as switches or amplifiers in simple control circuits.

传感电路常将热敏电阻和光敏电阻 (LDR) 作为分压器的一部分。输出设备包括 LED、蜂鸣器和继电器。晶体管可在简单控制电路中作为开关或放大器使用。
