Pont del Diable

Pont del Diable 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 Pont del Diable rather than just read about it. In short: The Pont del Diable (Spanish: Puente del Diablo, English: Devil's bridge), also known as Sant Bartomeu Bridge, is a medieval bridge crossing the river Llobregat and straddling the municipalities of Martorell and Castellbisbal in Catalonia, Spain. The bridge is restricted to pedestrians.

Key takeaways

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

Reference excerpt

The Pont del Diable (Spanish: Puente del Diablo, English: Devil's bridge), also known as Sant Bartomeu Bridge, is a medieval bridge crossing the river Llobregat and straddling the municipalities of Martorell and Castellbisbal in Catalonia, Spain. The bridge is restricted to pedestrians. The present bridge, featuring a large pointed arch, is a 1965 reconstruction of the gothic bridge built in 1283 on Roman foundations by Mohammed II Emir of Granada. The main clear span is 37.3 metres (122 ft) with a stone chapel on top. A secondary arch has a span of 19.1 metres (63 ft). The bridge was destroyed in 1939 during the Spanish Civil War by retreating Republican troops, but rebuilt in 1965 in a form generally similar to the gothic structure. It is now surrounded on three sides by road flyovers and railway lines. The original Roman bridge formed a part of the Via Augusta, and was the only bridge in the lower Llobregat valley until the 14th century. It still features a Roman triumphal arch at its eastern abutment. It is unclear how many spans the original Roman bridge had.

Worked examples

Example 1 — a first encounter with Pont del Diable

Start with the simplest possible case. Write down what Pont del Diable 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 Pont del Diable 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 Pont del Diable 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 Pont del Diable

In research: Pont del Diable 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 Pont del Diable 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: Pont del Diable is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bridges completed in the 13th century, Buildings and structures completed in 1283, Deck arch bridges, so understanding it makes those chapters shorter.
In everyday life: Look for Pont del Diable 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.
