Ron Jarvis

Ron Jarvis 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 Ron Jarvis rather than just read about it. In short: Ronald Guy Jarvis was a British locomotive engineer, born 5 November 1911 in Harpenden, Hertfordshire, England. Jarvis apprenticed at Derby Works under George Ivatt.

Key takeaways

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

Reference excerpt

Ronald Guy Jarvis was a British locomotive engineer, born 5 November 1911 in Harpenden, Hertfordshire, England. Jarvis apprenticed at Derby Works under George Ivatt.

Career

Wartime work During World War II Jarvis was sent to Turkey to oversee the assembly of the TCDD 45151 Class (LMS Stanier Class 8Fs), and then to India with William Stanier.

British Railways After the war, he worked briefly under Ivatt before being transferred to Brighton Works on the Southern Region of the newly nationalised British Railways, replacing Oliver Bulleid. From 1956, the Merchant Navy and West Country/Battle of Britain classes of his predecessor were rebuilt to a design set out by Jarvis, removing all eccentricities that had plagued the maintenance of these locomotives.

High Speed Train project Jarvis returned to Derby to oversee the development of the Class 43 InterCity 125 power cars.

Death Jarvis died in Llandudno on 2 September 1994, and was buried at Llanbedr.

Worked examples

Example 1 — a first encounter with Ron Jarvis

Start with the simplest possible case. Write down what Ron Jarvis 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 Ron Jarvis 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 Ron Jarvis 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 Ron Jarvis

In research: Ron Jarvis 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 Ron Jarvis 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: Ron Jarvis is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1911 births, 1994 deaths, 20th-century British engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Ron Jarvis 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.
