Portland Breakwater Light

Portland Breakwater Light 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 Portland Breakwater Light rather than just read about it. In short: The Portland Breakwater Light (also called Bug Light) is a small lighthouse in South Portland, Maine, United States. History A lighthouse was first built here in 1855 as a wooden structure.

Key takeaways

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

Reference excerpt

The Portland Breakwater Light (also called Bug Light) is a small lighthouse in South Portland, Maine, United States.

History A lighthouse was first built here in 1855 as a wooden structure. The breakwater was extended and a new lighthouse was constructed at the end of it in 1875. The new lighthouse was made of curved cast-iron plates whose seams are disguised by six decorative Corinthian columns. Its design was inspired by the Choragic Monument of Lysicrates in Athens, made well-known by engravings. The architect was Thomas U. Walter, most noted as the designer of the U.S. Capitol east and west wings and its current dome. Wooden sheds and a six-room house for the lighthouse-keeper were added incrementally as needed. In 1897, Spring Point Ledge Light was erected and the houses around Bug Light were demolished and the Spring Point Ledge Lighthouse keepers tended to both lighthouses. During World War II, the breakwater was slowly absorbed by landfill as the New England Shipbuilding Corporation built two shipyards next to the lighthouse. These shipyards produced Liberty Ships for the war effort. Because of the smaller breakwater, there was less need for the lighthouse and it was decommissioned in 1943.

Restoration The light was fully restored in 1989 and was reactivated in 2002. It appears as a private aid to navigation in the US Coast Guard Light List as South Portland Breakwater Light. A park named after the lighthouse, Bug Light Park, allows visitors to view the Portland Breakwater Light up close, while memorializing the shipbuilding efforts of World War II. The light was added to the National Register of Historic Places as Portland Breakwater Light on June 19, 1973, reference number 73000238.

Worked examples

Example 1 — a first encounter with Portland Breakwater Light

Start with the simplest possible case. Write down what Portland Breakwater Light 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 Portland Breakwater Light 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 Portland Breakwater Light 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 Portland Breakwater Light

In research: Portland Breakwater Light 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 Portland Breakwater Light 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: Portland Breakwater Light is common in secondary-school and first-year university syllabi. It links to neighbouring topics Breakwaters, Buildings and structures in South Portland, Maine, Lighthouses completed in 1855, so understanding it makes those chapters shorter.
In everyday life: Look for Portland Breakwater Light 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.
