Richard Mansell

Richard Mansell 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 Richard Mansell rather than just read about it. In short: Richard Christopher Mansell (October 1813 in Liverpool – 25 May 1904 in Long Marton, Westmorland) was an English railway engineer. Mansell was carriage superintendent for the South Eastern Railway at Ashford by 1851, and later works manager for the SER.

Key takeaways

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

Reference excerpt

Richard Christopher Mansell (October 1813 in Liverpool – 25 May 1904 in Long Marton, Westmorland) was an English railway engineer. Mansell was carriage superintendent for the South Eastern Railway at Ashford by 1851, and later works manager for the SER. In 1877 he succeeded Alfred Mellor Watkin as locomotive superintendent of the SER. When James Stirling was appointed in 1878, Mansell resumed the post of works manager until his retirement from the SER in January 1882. On leaving, he was given an annual consultancy fee/pension of fifty guineas.

Carriages R. C. Mansell was the inventor of the Mansell wheel, a composite wood and metal carriage wheel, for which he obtained patents in 1848, 1862 and 1866. Use of this design in preference to other methods of affixing tyres to wheels was often indicated following tyre and/or wheel incidents resulting in accidents by investigating officers of the Board of Trade, most notably following the accidents at Hatfield on the Great Northern Railway on Boxing Day (26 Dec) 1870 and Skipton-on-Cherwell on the Great Western Railway on Christmas Eve 1874. By 1874 there were over 20,000 sets of Mansell wheels in use.

Locomotives As locomotive superintendent, Mansell designed twelve locomotives: 9 0-4-4T in 1878 and 3 0-6-0 in 1879 (7 others were cancelled). Three 0-6-0Ts that had been designed by Cudworth were also completed under Mansell's supervision in 1877. None of his engines had a distinguished service life. The tank engines lasted about 12 years, and the 0-6-0s about twice as long.

Family Richard Christopher Mansell was the second of five children born to John Mansell, a Customs House Officer in Liverpool, and his wife Margaret Rothwell. Richard married twice. He married his first wife, Elizabeth Birchall Norris, 1816 Liverpool - March 1873 Ashford, Kent (died aged 56) at Edge Hill, Liverpool St Mary in 1836. They had three children: Margaret, James Thomas and James Rothwell. He married his second wife, Emmeline Aldgate Clark, 29 August 1833, St. Pancras, London - 29 August 1912, Long Marton, Westmorland at Camden Haverstock Hill Holy Trinity on 14 April 1874. They had two children: Albert and Emmeline.

Worked examples

Example 1 — a first encounter with Richard Mansell

Start with the simplest possible case. Write down what Richard Mansell 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 Richard Mansell 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 Richard Mansell 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 Richard Mansell

In research: Richard Mansell 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 Richard Mansell 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: Richard Mansell is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1813 births, 1904 deaths, Engineers from Liverpool, so understanding it makes those chapters shorter.
In everyday life: Look for Richard Mansell 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.
