Mobile Land Mine

Mobile Land Mine 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 Mobile Land Mine rather than just read about it. In short: The Mobile Land Mine (originally named "Beetle") was an experimental British World War II remote-controlled tracked explosive device. It was wire guided and powered by two electric motors.

Key takeaways

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

Reference excerpt

The Mobile Land Mine (originally named "Beetle") was an experimental British World War II remote-controlled tracked explosive device. It was wire guided and powered by two electric motors.

History The Mobile Land Mine was designed by Metropolitan-Vickers in 1940. After a successful demonstration in August 1941 an order for 50 was placed so that trials could be carried out. In 1942 Commander-in-Chief, Home Forces reported that it was not recommended as there was no requirement for it. It was underpowered, slow, the motors overheated and it couldn't cross typical battlefield terrain. It was rejected by the General Staff in 1944. Among other trials a Mobile Land Mine was waterproofed and equipped with floats allowing it to be used against landing craft.

Worked examples

Example 1 — a first encounter with Mobile Land Mine

Start with the simplest possible case. Write down what Mobile Land Mine 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 Mobile Land Mine 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 Mobile Land Mine 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 Mobile Land Mine

In research: Mobile Land Mine 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 Mobile Land Mine 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: Mobile Land Mine is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940s robots, Explosive weapons, Robotics stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Mobile Land Mine 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.
