La Grange Lock and Dam

La Grange Lock and Dam 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 La Grange Lock and Dam rather than just read about it. In short: LaGrange Lock and Dam is a lock and dam complex on the Illinois River at Versailles, Illinois. The structure includes a 1,066 feet (325 m) dam and a 110 by 600 feet (34 by 183 m) lock.

Key takeaways

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

Reference excerpt

LaGrange Lock and Dam is a lock and dam complex on the Illinois River at Versailles, Illinois. The structure includes a 1,066 feet (325 m) dam and a 110 by 600 feet (34 by 183 m) lock. The U.S. Army Corps of Engineers built the complex from 1936 to 1939; A.F. Griffin designed the lock and dam, while Paul Le Gromwell designed the control station. The lock and dam, as well as a similar lock and dam near Peoria, were needed when the authorized channel depth was raised to nine foot. The Peoria and LaGrange locks replaced older locks on the lower Illinois River. The lock uses Chanoine wicket gates, which allow for navigation on the river, rather than the Tainter gates seen elsewhere on the river. The structure was added to the National Register of Historic Places on March 10, 2004.

Worked examples

Example 1 — a first encounter with La Grange Lock and Dam

Start with the simplest possible case. Write down what La Grange Lock and Dam 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 La Grange Lock and Dam 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 La Grange Lock and Dam 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 La Grange Lock and Dam

In research: La Grange Lock and Dam 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 La Grange Lock and Dam 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: La Grange Lock and Dam is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures completed in 1939, Buildings and structures in Brown County, Illinois, Central Illinois Registered Historic Place stubs, so understanding it makes those chapters shorter.
In everyday life: Look for La Grange Lock and Dam 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.
