Reference excerpt

The Military Obelisk of Brasília is a monument in Brazil erected at the Army Headquarters in front of the Concha Acústica in Brasília, the Federal District.

Background and purpose of the monument Oscar Niemeyer first incorporated an obelisk into one of his works when he participated in the competition organized by the Ministry of Education and Health to select a project for the National Athletic Center in Rio de Janeiro. Niemeyer's project was not built. In 1949, Niemeyer also designed the Monument to Ruy Barbosa in Rio de Janeiro, which was not constructed either. He later revisited the project, and the obelisk was finally constructed in 1967 in the new capital. The military named it the "Sword of Duque de Caxias." The monument was erected in Brasília to honor Luís Alves de Lima e Silva, Duke of Caxias, the patron of the Brazilian Army.

Architecture

The architectural design of the monument dedicated to Duke of Caxias, known as the Acoustic Shell, includes an obelisk in the front. The combination of these two elements symbolically represents the hilt and blade of the patron of the Brazilian Army's sword. According to Vitruvios, a magazine specializing in architecture, the project was signed by Oscar Niemeyer and is characterized as follows:

The Army Headquarters, in the Urban Military Sector, the "Forte Caxias," is a late work. The grand and austere complex, with a sequence of parallel buildings, harks back to the fortifications of the first civilizations of antiquity, with their walls erected for the protection of palaces and temples. Between the headquarters and the street in front, there are: a large concrete cover tending toward an elliptical shape that forms a platform; and an obelisk – a reinterpretation of the Egyptian obelisks that were incorporated into temples at their entrances.

Worked examples

Example 1 — a first encounter with Military Obelisk of Brasilia

Start with the simplest possible case. Write down what Military Obelisk of Brasilia 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 Military Obelisk of Brasilia 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 Military Obelisk of Brasilia 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 Military Obelisk of Brasilia

In research: Military Obelisk of Brasilia 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 Military Obelisk of Brasilia 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: Military Obelisk of Brasilia is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1967 establishments in Brazil, Brazilian Army, Buildings and structures completed in 1967, so understanding it makes those chapters shorter.
In everyday life: Look for Military Obelisk of Brasilia 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.
