📚 Year 10 Eduqas Engineering: Practical Assessment Key Points | Year 10 Eduqas 工程：实验/实践考核要点

Practical assessments in Year 10 Engineering focus on developing essential workshop skills, safe working habits, and the ability to follow a design process from drawing to finished product. These key points will help you prepare for internal practical tests and build a strong foundation for your NEA.

Year 10 工程实践评估的重点是培养必要的车间技能、安全工作习惯，以及遵循从图纸到成品的整个设计流程的能力。这些要点将帮助你为校内实践测试做好准备，并为非考试评估（NEA）打下坚实基础。

1. Health and Safety in the Workshop | 车间健康与安全

Before any practical task, you must identify hazards and follow safe working practices. Always wear appropriate Personal Protective Equipment (PPE) such as safety goggles, gloves, and steel-toe boots when working in the workshop. Long hair must be tied back and loose clothing secured.

在进行任何实践任务之前，必须识别危险并遵守安全作业规范。在车间工作时，始终佩戴适当的个人防护装备（PPE），如安全护目镜、手套和钢头鞋。长发必须束于脑后，宽松衣物应妥善固定。

Ensure that all machine guards are in place and you know the location of emergency stop buttons before operating any machinery. If an accident occurs, report it immediately to the teacher or technician.

在操作任何机器之前，确保所有机器防护罩都就位，并且你知道紧急停止按钮的位置。如果发生事故，立即向老师或技师报告。

2. Reading Engineering Drawings | 阅读工程图纸

Engineering drawings use orthographic projection to show the shape of an object from different views, typically front, side and plan. Make sure you understand the symbol for third-angle projection and can identify hidden details shown as dashed lines.

工程图纸使用正投影从不同视图显示物体的形状，通常是前视图、侧视图和平面图。要确保你理解第三角投影的符号，并能识别虚线所示的隐藏细节。

Always check dimensions and tolerances on the drawing; a tolerance of ±0.5 mm means the part can be 0.5 mm larger or smaller than the nominal size. Look out for surface finish symbols and notes on material and finish.

始终检查图纸上的尺寸和公差；±0.5mm的公差意味着零件可以比标准尺寸大或小0.5mm。注意表面粗糙度符号以及关于材料和表面处理的注释。

3. Material Selection and Properties | 材料选择与特性

Choosing the right material is crucial. Common engineering materials in schools include mild steel, aluminium, acrylic, and plywood. Consider mechanical properties such as tensile strength, hardness, ductility, and machinability.

选择正确的材料至关重要。学校常见的工程材料包括低碳钢、铝、亚克力和胶合板。要考虑拉伸强度、硬度、延展性和可加工性等机械性能。

The table above shows some common materials and their properties. When selecting for a project, also consider cost, availability, and the joining methods you will use.

4. Marking Out and Measuring | 划线与测量

Accurate marking out is essential for producing parts that fit together correctly. Use a steel rule and scriber to mark lines, and an engineer’s square or a try square to ensure lines are perpendicular to an edge.Published by TutorHao | Year 10 工程 Revision Series | aleveler.com
