Mesta Machinery

Mesta Machinery is a science 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 Mesta Machinery rather than just read about it. In short: Mesta Machinery was a leading industrial machinery manufacturer based in the Pittsburgh area town of West Homestead, Pennsylvania. It was founded in 1898 by George Mesta when he merged his machine shop with another.

Key takeaways

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

Reference excerpt

Mesta Machinery was a leading industrial machinery manufacturer based in the Pittsburgh area town of West Homestead, Pennsylvania. It was founded in 1898 by George Mesta when he merged his machine shop with another. Mesta "machines" can be found in factories throughout the world and as of 1984 had equipment in 500 steel mills. Mesta was the 488th largest American company in 1958 and the 414th largest in 1959.

President Mesta By 1919 Mesta employed 3,000 at West Homestead and manufactured everything from ship propeller shafts to giant turbines for power plants and dams. In 1917, George's wife Perle Mesta wrote that the works "was a thrilling site, spread over many acres on the banks of the Monongahela." George Mesta died in 1925.

President Wahr Harry F. Wahr was the handpicked successor to Mesta and his nephew. Wahr committed suicide in 1930.

President Iversen Lorenz Iversen took over the company in 1930, leading it until December 31, 1963. One of the first things Iversen accomplished in the early 1930s was to buy Perle Mesta's controlling preferred stock, effectively buying the company from her. Iversen was a native of Denmark and immigrated to the US. He worked in a factory in New Jersey before returning to Denmark to get his degree in engineering, then worked at Mesta as a draftsman in 1903. Prior to 1930 he became chief engineer and held patents on devices integral to every machine manufactured by Mesta, allowing him to establish $4 million trusts ($94 million today) for each of his five children by 1932. Mesta won the contract to build the Mon Valley Works–Irvin Plant for U.S. Steel in 1934.

Management style Iversen was described by many former employees as the glue that held Mesta together. In the 1930s he won a large contract with a steel manufacturer by foregoing the company's standard fee in exchange for a share of the profits of the manufactured mill. He would regularly cheer on his workers and had a ritual of standing on a hastily made stage every time Mesta won a new contract and exclaiming: "We got this job because you’re the best mechanics in the world!" He often had face-to-face talks with employees and would work the factory floor on weekends, holidays and Christmas, asking workers about new babies or ailing family members. Mesta workers repeatedly voted down efforts to unionize the factory despite its proximity to unionized steel mills including the (infamous in labor history) Homestead Mill. Iversen credited his employment policy based on human relations as the chief reason his workers rejected unionization. A month after his death in 1967 (and four years after he stepped down as president) Mesta was unionized.

World War II Mesta's West Homestead plant was a center for WWII production. It earned the Army-Navy E Award, and was one of seven factories to earn six stars. Mesta specialized in manufacturing 16-inch naval guns, ship-propeller shafts, artillery carriages and "Long Toms" 155-mm cannons. Iversen personally oversaw the production of "Little David", a 36-inch bore mortar that was put into production for the canceled Japanese invasion. During the war, Iversen transformed Mesta into one of the nation's top ordnance suppliers, personally working 18-hour shifts in the factory. His accounting department also ran two 8-hour shifts per day. Mesta, and later Iverson, operated the Hays Army Ammunition Plant from the 1940s through the 1960s.

Post war success

The company manufactured a 50,000 ton press (the "fifty") as part of the Heavy Press Program, initially owned by the Air Force in 1952 and operated by Alcoa, which purchased it outright in 1982. The press manufactures structural components for aircraft such as the 747 and DC-10 jetliners. After being taken out of service due to cracking in the structure, it was refurbished over three years at a cost of $100 million, and returned to service in 2012.

Khrushchev visit In September 1959, Nikita Khrushchev visited the Mesta Machinery Co. factory on his tour of the U.S., where he received a cigar from a worker.

Demise Mesta filed for bankruptcy in February 1983, and most of its West Homestead works was sold off in June 1983. The company's last assets were sold in April 1988. The property in West Homestead where Mesta Machinery was located is (as of 2018) mostly occupied by Whemco Steel Castings. Whemco manufactures heavy industrial equipment, much like the products of the former Mesta Machinery. A spin-off company called Mestek briefly had some success. After reorganization the remaining units were the former in house engineering and computer services departments. The company was publicly listed and had tax benefits from loss carry forwards. Mestek was used as a corporate vehicle by Reed National.

Worked examples

Example 1 — a first encounter with Mesta Machinery

Start with the simplest possible case. Write down what Mesta Machinery claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Mesta Machinery 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 Mesta Machinery 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 Mesta Machinery

In research
Mesta Machinery appears in science 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 Mesta Machinery 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
Mesta Machinery is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1898 establishments in Pennsylvania, Defunct companies based in Pennsylvania, Machine manufacturers, so understanding it makes those chapters shorter.
In everyday life
Look for Mesta Machinery 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.
