Peace Candle of the World

Peace Candle of the World 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 Peace Candle of the World rather than just read about it. In short: The Peace Candle of the World, also known as the Scappoose Peace Candle, is an approximately 50-foot-tall (15 m) tower-like structure 18 feet (5.5 m) in diameter in Scappoose, Oregon, designed to resemble a candle. It was built in 1971 outside what was then the Brock Candles Inc. factory, which burned down in 1990.

Key takeaways

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

Reference excerpt

The Peace Candle of the World, also known as the Scappoose Peace Candle, is an approximately 50-foot-tall (15 m) tower-like structure 18 feet (5.5 m) in diameter in Scappoose, Oregon, designed to resemble a candle. It was built in 1971 outside what was then the Brock Candles Inc. factory, which burned down in 1990. The land was formerly a dairy farm; factory owner Darrel Brock created the candle by covering a silo with 45,000 pounds (20 t) of red candle wax to advertise the factory. The candle was originally built with an actual wick. On May 9, 1971, the town's mayor and Oregon Governor Tom McCall lit the candle with a specially-made 60-foot-long match. President Richard Nixon declined a request to light the candle. Due to difficulties in keeping the candle lit during rainfall, the wick was replaced with a natural gas line up the center of the candle to create a real flame at the top. However, due to environmental concerns and high gas bills, the flame was eventually replaced with an electric neon light flame structure. The Peace Candle of the World was awarded the Guinness World Record for world's largest candle, but the record was later given to the 127-foot (39 m) wax candle that was featured at the General Art and Industrial Exhibition of Stockholm in 1897. The Scappoose Peace Candle sits on the east side of U.S. Route 30 and is visible from the highway. Each season the candle was re-coated with different colors to match the time of year, with red for Christmas and multiple colors being used in the fall. The wax around the candle was eventually replaced with more durable wax-like substances. The candle is meant to serve as a symbol for the desire for world peace. During the Christmas season the Scappoose Peace Candle is strewn with strands of Christmas lights. The Scappoose region around the Peace Candle of the World has become more and more developed in recent years, and local residents fear that the candle could be demolished for redevelopment. In June 2015 the Weather Channel website selected the Peace Candle of the World as the Oregon selection for its "Most Incredible Roadside Attraction in Every State" list.

Worked examples

Example 1 — a first encounter with Peace Candle of the World

Start with the simplest possible case. Write down what Peace Candle of the World 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 Peace Candle of the World 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 Peace Candle of the World 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 Peace Candle of the World

In research: Peace Candle of the World 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 Peace Candle of the World 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: Peace Candle of the World is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1971 establishments in Oregon, Buildings and structures completed in 1971, Buildings and structures in Columbia County, Oregon, so understanding it makes those chapters shorter.
In everyday life: Look for Peace Candle of the World 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.
