Salt Lake meridian

Salt Lake meridian 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 Salt Lake meridian rather than just read about it. In short: The Salt Lake meridian, established in 1855, in longitude 111° 54′ 00″ west from Greenwich, has its initial point at southeast corner of Temple Square, in Salt Lake City, Utah, extends north and south through the state, and, with the base line, through the initial, and coincident with the parallel of 40° 46′ 04″ north latitude, governs the surveys in the territory, except those referred to the Uintah meridian and Ba…

Key takeaways

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

Reference excerpt

The Salt Lake meridian, established in 1855, in longitude 111° 54′ 00″ west from Greenwich, has its initial point at southeast corner of Temple Square, in Salt Lake City, Utah, extends north and south through the state, and, with the base line, through the initial, and coincident with the parallel of 40° 46′ 04″ north latitude, governs the surveys in the territory, except those referred to the Uintah meridian and Baseline projected from an initial point in latitude 40° 26′ 20″ north, longitude 109° 57′ 30″ west from Greenwich.

Worked examples

Example 1 — a first encounter with Salt Lake meridian

Start with the simplest possible case. Write down what Salt Lake meridian 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 Salt Lake meridian 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 Salt Lake meridian 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 Salt Lake meridian

In research: Salt Lake meridian 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 Salt Lake meridian 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: Salt Lake meridian is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1855 establishments in Utah Territory, Geography of Utah, Historic American Engineering Record in Utah, so understanding it makes those chapters shorter.
In everyday life: Look for Salt Lake meridian 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.
