Marsh Engineering Company

Marsh Engineering Company 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 Marsh Engineering Company rather than just read about it. In short: The Marsh Engineering Company was a company that designed many significant bridges in the United States, including a number that survive and are listed on the National Register of Historic Places. It was located at 206 Masonic Temple in Des Moines, Iowa.

Key takeaways

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

Reference excerpt

The Marsh Engineering Company was a company that designed many significant bridges in the United States, including a number that survive and are listed on the National Register of Historic Places. It was located at 206 Masonic Temple in Des Moines, Iowa. The firm's principal engineer was James Barney Marsh (1856–1936), an engineer and bridge designer born in North Lake, Wisconsin. Works include:

Dunkerton Bridge (1909), Town street over Crane Creek, Dunkerton, Iowa (NRHP-listed)

Marsh Concrete Rainbow Arch Bridge (1911), Courtland, Minnesota, is a reinforced concrete through arch bridge, built in 1911 the same year that Marsh obtained a patent for his design. (NRHP-listed) Rainbow Arch Bridge at Valley City, North Dakota, (was NRHP-listed but was later removed) Squaw Creek Bridge (1917), 120th St. and V Ave. over Squaw Creek, Ridgeport, Iowa (NRHP-listed) Mederville Bridge (1918), County road over Volga River, Mederville, Iowa (NRHP-listed) First Avenue Bridge (1920), US 151 over Cedar River, Cedar Rapids, Iowa (NRHP-listed) Rainbow Arch Bridge (1922), CO 52, Fort Morgan, Colorado (NRHP-listed) River Street Bridge (1922-24), Iowa Falls, Iowa (NRHP-listed)

Cotter Bridge, constructed in 1930, is the only bridge built by Marsh Engineering Company of Des Moines, Iowa in the state of Arkansas. It brings U.S. Route 62, over the White River, and opened up a large area of the Ozarks for recreation. (NRHP-listed)

Henley Street Bridge, in Knoxville, Tennessee, designed in 1930 The Wilson River Bridge (1931), near Tillamook, Washington, and others like it in Washington were designed by notable architect Conde McCullough, who had been employed at Marsh Engineering Company during the 1910s.

Worked examples

Example 1 — a first encounter with Marsh Engineering Company

Start with the simplest possible case. Write down what Marsh Engineering Company 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 Marsh Engineering Company 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 Marsh Engineering Company 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 Marsh Engineering Company

In research: Marsh Engineering Company 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 Marsh Engineering Company 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: Marsh Engineering Company is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1909 establishments in Iowa, American architect stubs, American companies established in 1909, so understanding it makes those chapters shorter.
In everyday life: Look for Marsh Engineering Company 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.
