Lord Block

Lord Block 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 Lord Block rather than just read about it. In short: The Lord Block is a historic commercial building in downtown Lewiston, Maine. Built in 1865, it is one of downtown Lewiston's oldest commercial buildings, and a reminder of the city's early commercial character.

Key takeaways

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

Reference excerpt

The Lord Block is a historic commercial building in downtown Lewiston, Maine. Built in 1865, it is one of downtown Lewiston's oldest commercial buildings, and a reminder of the city's early commercial character. The building was listed on the National Register of Historic Places in 1986.

Description and history The Lord Block is located on the southern half of Lisbon Street, Lewiston's main business district, at the southwest corner of Lisbon and Cedar Streets. It is a 2-1/2 story masonry structure, built out of load-bearing brick with granite trim, with a front-facing gable roof that has a cross gable on the north side. The front has two virtually identical storefronts, each with a recessed entrance on the left and a plate glass display window to the right. The doors and windows are separated by rusticated granite piers, with a modern awning now extending across both storefronts and on to the adjacent building. Upper floor and side facade windows are sash windows set in rectangular openings, with granite sills and lintels. The north-facing gable is finished in decorative cut shingles, and has two window bays. The building was constructed in 1865 for James C. and Rufus Lord, dealers in "provisions", and was probably one of the first commercial businesses on the southern stretch of Lisbon Street, near the mills. Its deed restrictions limited its height, and required masonry construction. The store was apparently successful: James Lord was able to build an elaborate house on Main Street in 1885.

Worked examples

Example 1 — a first encounter with Lord Block

Start with the simplest possible case. Write down what Lord Block 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 Lord Block 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 Lord Block 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 Lord Block

In research: Lord Block 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 Lord Block 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: Lord Block is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures completed in 1865, Buildings and structures in Lewiston, Maine, Commercial buildings on the National Register of Historic Places in Maine, so understanding it makes those chapters shorter.
In everyday life: Look for Lord Block 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 Lord Block in simple terms?

Why does Lord Block 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.
