Tour Sequoia

Tour Sequoia 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 Tour Sequoia rather than just read about it. In short: Tour Sequoia (previously known as tour Bull, and also known as tour SFR or tour Cegetel) is an office skyscraper located in La Défense business district just west of Paris, France. Built in 1990, the 119-metre-tall tower represents the transition between the third and the fourth generations of buildings in La Défense.

Key takeaways

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

Reference excerpt

Tour Sequoia (previously known as tour Bull, and also known as tour SFR or tour Cegetel) is an office skyscraper located in La Défense business district just west of Paris, France. Built in 1990, the 119-metre-tall tower represents the transition between the third and the fourth generations of buildings in La Défense. It is the first tower to be built with a semi-circular design in the business district. The design later inspired other towers such as CBC, Kupka, Pacific, Société Générale twin towers, and Tour CBX. Tour Sequoia has been built in proximity with the CNIT and the Grande Arche.

Worked examples

Example 1 — a first encounter with Tour Sequoia

Start with the simplest possible case. Write down what Tour Sequoia 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 Tour Sequoia 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 Tour Sequoia 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 Tour Sequoia

In research: Tour Sequoia 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 Tour Sequoia 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: Tour Sequoia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures completed in 1990, Office buildings completed in 1990, Skyscraper office buildings in La Défense, so understanding it makes those chapters shorter.
In everyday life: Look for Tour Sequoia 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.

Frequently asked questions

What is Tour Sequoia in simple terms?

Why does Tour Sequoia matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Tour Sequoia?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
