Mrs Macquarie's Chair

Mrs Macquarie's Chair 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 Mrs Macquarie's Chair rather than just read about it. In short: Mrs Macquarie's Chair (also known as Lady Macquarie's Chair) is an exposed sandstone rock cut into the shape of a bench, on a peninsula in Sydney Harbour. It was hand carved by convicts in 1810, for Elizabeth Macquarie, the wife of Major-General Lachlan Macquarie, Governor of New South Wales.

Key takeaways

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

Reference excerpt

Mrs Macquarie's Chair (also known as Lady Macquarie's Chair) is an exposed sandstone rock cut into the shape of a bench, on a peninsula in Sydney Harbour. It was hand carved by convicts in 1810, for Elizabeth Macquarie, the wife of Major-General Lachlan Macquarie, Governor of New South Wales. The peninsula itself was known to the Gadigal as Yurong Point, and is now widely known as Mrs Macquarie's Point, and is part of The Domain, near the Royal Botanic Gardens.

Description Mrs Macquarie was the wife of Major-General Lachlan Macquarie, Governor of New South Wales from 1810 to 1821. Folklore has it that she used to sit on the rock and watch for ships from Great Britain sailing into the harbour. She was known to visit the area and sit enjoying the panoramic views of the harbour. Above the chair is a stone inscription referring to Mrs Macquarie's Road. That road was built between 1813 and 1818, and ran from the original Government House (now the Museum of Sydney) to Mrs Macquarie's Point. It was built on the instruction of Governor Macquarie for the benefit of his wife. There is no remaining evidence of the original road, other than a culvert over which the road ran—the Macquarie Culvert. The stone inscription reads as follows.

Be it thus Recorded that the Road Round the inside of the Government Domain Called Mrs. Macquarie's road So named by the Governor on account of her having Originally Planned it Measuring 3 Miles, and 377 Yards Was finally Completed on the 13th Day ofJune 1816 The peninsula sits between the Garden Island peninsula to the east and Bennelong Point (where the Sydney Opera House resides) to the west. The chair itself faces north-east towards Fort Denison and the Tasman Sea. The area around it on Mrs Macquarie's Point is a popular lookout position for the view to the north-west of the Sydney Opera House and Sydney Harbour Bridge.

Worked examples

Example 1 — a first encounter with Mrs Macquarie's Chair

Start with the simplest possible case. Write down what Mrs Macquarie's Chair 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 Mrs Macquarie's Chair 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 Mrs Macquarie's Chair 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 Mrs Macquarie's Chair

In research: Mrs Macquarie's Chair 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 Mrs Macquarie's Chair 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: Mrs Macquarie's Chair is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bench monuments, Buildings and structures completed in 1810, Individual chairs, so understanding it makes those chapters shorter.
In everyday life: Look for Mrs Macquarie's Chair 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.
