Mingun Bell

Mingun Bell 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 Mingun Bell rather than just read about it. In short: The Mingun Bell (မင်းကွန်းခေါင်းလောင်းတော်ကြီး [mɪ́ɰ̃ɡʊ́ɰ̃ kʰáʊɰ̃láʊɰ̃ dɔ̀ dʑí]) is a bell located in Mingun, Sagaing Region, Myanmar. It is located approximately 11 km (6.8 mi) north of Mandalay on the western bank of the Irrawaddy River.

Key takeaways

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

Reference excerpt

The Mingun Bell (မင်းကွန်းခေါင်းလောင်းတော်ကြီး [mɪ́ɰ̃ɡʊ́ɰ̃ kʰáʊɰ̃láʊɰ̃ dɔ̀ dʑí]) is a bell located in Mingun, Sagaing Region, Myanmar. It is located approximately 11 km (6.8 mi) north of Mandalay on the western bank of the Irrawaddy River. It was the heaviest functioning bell in the world at several times in history. The Mingun Bell was built on the orders of Burmese King Bodawpaya (r. 1782–1819) and was cast in bronze in 1808 as part of his massive temple complex project in Mingun, Myanmar. Bodawpaya sought to create the world's largest ringing bell, commissioning it with an alloy of gold, silver, bronze, iron, and lead, weighing over 90 metric tons (55,555 viss).

Description The weight of the bell is 55,555 viss (90,718 kilograms or 199,999 pounds). This number is conveniently remembered by many people in Myanmar as a mnemonic "Min Hpyu Hman Hman Pyaw" (မင်းဖြူမှန်မှန်ပြော), with the consonants representing the number 5 in Burmese astronomy and numerology. The weight of the bell and its mnemonic words are written on the surface of the bell in white.

The outer diameter of the rim of the bell is 16 feet 3 inches (4.95 m). The height of the bell is 12.0 feet (3.66 m) on the exterior and 11.5 feet (3.51 m) in the interior. The outside circumference at the rim is 50.75 feet (15.469 m). The bell is 6 to 12 inches (15–30 cm) thick and stands 20.7 feet (6.31 m) high from the rim to the top. The bell is uncracked and in good ringing condition. The bell does not have a clapper but is rung by striking the outer edge.

History Casting of the bell started in 1808 and was finished by 1810. King Bodawpaya (r. 1782–1819) had this gigantic bell cast to go with his huge stupa, Mingun Pahtodawgyi. The bell was said to have been cast on the opposite side of the river and was transported by using two boats, which after crossing the river, proceeded up two specially built canals. The canals were then dammed and the bell was lifted by raising the water level by the addition of earth into the blocked canal. In this way the bell was originally suspended. The Mingun Bell was knocked off its supports as a result of a large earthquake on 23 March 1839. It was resuspended by the Irrawaddy Flotilla Company in March 1896 using screw jacks and levers using funds from public subscription. Felice Beato captured a photograph of the bell prior to its resuspension.

Current status At 90 tons, the Mingun Bell reigned as the largest ringing bell in the world until 2000, when it was eclipsed by the 116-ton Bell of Good Luck at the Foquan Temple, Pingdingshan, Henan, China.

Worked examples

Example 1 — a first encounter with Mingun Bell

Start with the simplest possible case. Write down what Mingun Bell 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 Mingun Bell 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 Mingun Bell 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 Mingun Bell

In research: Mingun Bell 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 Mingun Bell 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: Mingun Bell is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buddhist art, Buildings and structures completed in 1810, Culture of Myanmar, so understanding it makes those chapters shorter.
In everyday life: Look for Mingun Bell 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.
