Sierra (motor ship)

Sierra (motor ship) 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 Sierra (motor ship) rather than just read about it. In short: Sierra is a historic motor ship used to transport lumber. Built in 1916, it was added to the National Register of Historic Places in 1978.

Key takeaways

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

Reference excerpt

Sierra is a historic motor ship used to transport lumber. Built in 1916, it was added to the National Register of Historic Places in 1978.

History Sierra was built at Matthews shipyard in Hoquiam for E. K. Wood Lumber Company and was the first motor ship built on Grays Harbor. The ship's engines were made in Sweden by Bolinder, which sent a representative to oversee their installation. Senator Miles Poindexter attended the ship's launch on August 30, 1916. Its first long voyage was to Valparaíso, Chile. Sierra was able to complete the round-trip without refueling. Sierra was used to ferry lumber between Bellingham, Washington and Hoquiam, Washington. In one month in 1920, Sierra carried a shipment of 1,200,000 feet of lumber out of Bellingham. On Feb 7, 1923, Sierra was badly damaged after colliding with the steamship Wilhemina in dense fog near San Francisco; damages were estimated at $135,000. In 1926, Sierra caught fire at Berth 77 in the Port of Los Angeles, the first fire fought by the fireboat Los Angeles City No. 2. Sierra was sold in 1927 and equipped with refrigeration equipment to carry reindeer meat from Alaska for the Arctic Transport Company. During World War II, the U.S. Army operated Sierra as a training ship. After the war, Sierra was assigned to the Maritime Commission reserve fleet at Olympia, Washington, then later sold and transferred to Lake Union. In 1964, the new owner began restoring Sierra to its original, lumber-carrying configuration.

Worked examples

Example 1 — a first encounter with Sierra (motor ship)

Start with the simplest possible case. Write down what Sierra (motor ship) 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 Sierra (motor ship) 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 Sierra (motor ship) 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 Sierra (motor ship)

In research: Sierra (motor ship) 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 Sierra (motor ship) 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: Sierra (motor ship) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures completed in 1916, Lumber ships, National Register of Historic Places in Grays Harbor County, Washington, so understanding it makes those chapters shorter.
In everyday life: Look for Sierra (motor ship) 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.
