Johann Rihosek

Johann Rihosek 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 Johann Rihosek rather than just read about it. In short: Johann Rihosek (5 June 1869 – 21 November 1956) was an Austrian engineer and locomotive designer. He was born in Maków Podhalański, in Austro-Hungarian Galicia (present-day Poland) on 5 June 1869.

Key takeaways

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

Reference excerpt

Johann Rihosek (5 June 1869 – 21 November 1956) was an Austrian engineer and locomotive designer. He was born in Maków Podhalański, in Austro-Hungarian Galicia (present-day Poland) on 5 June 1869. Rihosek attended the middle school at Olmütz and later studied mechanical engineering at the Vienna Technical University.

Career In 1893 he took up his post as a design engineer with the Wiener Lokomotivfabrik Floridsdorf. From 1897 he worked in the Department for Locomotive and Coach Construction headed by Karl Gölsdorf within the Imperial Royal Railway Ministry. After Gölsdorf's death in 1916 Rihosek became his successor. The First World War and its consequences placed heavy demands on Rihosek, because the lack of materials led to problems in the manufacture of vehicles. Following the dividing up of the locomotive fleet to the new states formed from the breakup of the Austro-Hungarian empire, replacements had to be procured. This resulted in the emergence of the following classes:

ÖBB 156 (BBÖ 270) ÖBB 58 (BBÖ 81) ÖBB 95 (BBÖ 82) In 1924 Rihosek left the ministry (now called the Ministry for Trade and Transport) and became an honorary lecturer for locomotive construction at the Vienna Technical University. In 1936 he became reader there and in 1944 received an honorary doctorate.

Innovations Rihosek won special acclaim for his development of railway brakes, where he preferred the use of compressed air brakes. He carried out this work in conjunction with the firm of Gebrüder Hardy A.G., on whose board he sat until his death. In addition he invented the spark arrestor and the exhaust steam preheater.

Publications He published numerous articles in the magazines Organ für Fortschritte des Eisenbahnwesens, Zeitschrift des österreichischen Ingenieur- und Architektenverein, Die Lokomotive and Eisenbahn.

Death Rihosek died on 21 November 1956 in Vienna.

Worked examples

Example 1 — a first encounter with Johann Rihosek

Start with the simplest possible case. Write down what Johann Rihosek 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 Johann Rihosek 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 Johann Rihosek 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 Johann Rihosek

In research: Johann Rihosek 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 Johann Rihosek 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: Johann Rihosek is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1869 births, 1956 deaths, Austrian people of Polish descent, so understanding it makes those chapters shorter.
In everyday life: Look for Johann Rihosek 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.
