Seizing

Seizing is a science 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 Seizing rather than just read about it. In short: Seizings are a class of stopping knots used to semi-permanently bind together two ropes, two parts of the same rope, or rope and another object. Akin to lashings, they use string or small-stuff to produce friction and leverage to immobilize larger ropes.

Key takeaways

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

Reference excerpt

Seizings are a class of stopping knots used to semi-permanently bind together two ropes, two parts of the same rope, or rope and another object. Akin to lashings, they use string or small-stuff to produce friction and leverage to immobilize larger ropes. Seizings are not recommended for heavy loads for critical use as strain reduces the diameter of the main rope and can permit slippage even with proper construction. According to The Ashley Book of Knots, "A seizing holds several objects together." The other type of stopping knots are whipping knots.

A throat seizing is a seized round turn. It is used when turning in deadeyes, and has riding turns but no crossing turns. The end of the stay or shroud should first be stopped around the deadeye. -- The Ashley Book of Knots

Worked examples

Example 1 — a first encounter with Seizing

Start with the simplest possible case. Write down what Seizing claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Seizing 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 Seizing 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 Seizing

In research: Seizing appears in science 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 Seizing 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: Seizing is common in secondary-school and first-year university syllabi. It links to neighbouring topics Knot stubs, Knots, so understanding it makes those chapters shorter.
In everyday life: Look for Seizing 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 Seizing in simple terms?

Why does Seizing matter?

Because it connects several science 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.

How should I study Seizing?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
