Tongji Bridge (Yi County)

Tongji Bridge (Yi County) is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tongji Bridge (Yi County) rather than just read about it. In short: The Tongji Bridge (simplified Chinese: 通济桥; traditional Chinese: 通濟橋; pinyin: Tōngjì Qiáo), commonly known as North Gate Bridge (北门桥; 北門橋; Běimén Qiáo), is a historic stone arch bridge over the Zhang River in the town of Biyang, Yi County, Anhui, China. The bridge measures 32 metres (105 ft) long, 6.5 metres (21 ft) wide, and approximately 10 metres (33 ft) high.

Key takeaways

Tongji Bridge (Yi County) belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Tongji Bridge (Yi County) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Tongji Bridge (Yi County) from memory before moving on to harder problems.

Reference excerpt

The Tongji Bridge (simplified Chinese: 通济桥; traditional Chinese: 通濟橋; pinyin: Tōngjì Qiáo), commonly known as North Gate Bridge (北门桥; 北門橋; Běimén Qiáo), is a historic stone arch bridge over the Zhang River in the town of Biyang, Yi County, Anhui, China. The bridge measures 32 metres (105 ft) long, 6.5 metres (21 ft) wide, and approximately 10 metres (33 ft) high.

History The original bridge dates back to 1178, during the Chunxi period of the Southern Song dynasty (1127–1279), and rebuilt in 1541, during the ruling of Jiajing Emperor of the Ming dynasty (1368–1644). In the 19th year of Qianlong period (1754) of the Qing dynasty (1644–1911), it was rebuilt again and changed to its current name. It was renovated and refurbished in 1883 and 1982, respectively.

Worked examples

Example 1 — a first encounter with Tongji Bridge (Yi County)

Start with the simplest possible case. Write down what Tongji Bridge (Yi County) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tongji Bridge (Yi County) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tongji Bridge (Yi County) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tongji Bridge (Yi County)

In research: Tongji Bridge (Yi County) appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tongji Bridge (Yi County) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tongji Bridge (Yi County) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1750s establishments in China, 1754 establishments in Asia, Arch bridges in China, so understanding it makes those chapters shorter.
In everyday life: Look for Tongji Bridge (Yi County) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
