Tokai Challenger

Tokai Challenger is a astronomy 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 Tokai Challenger rather than just read about it. In short: Tokai Challenger is a solar car from the Japanese Tokai University. The Tokai Challenger became the winner of the 2009 and 2011 World Solar Challenge, a race for solar cars across Australia.

Key takeaways

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

Reference excerpt

Tokai Challenger is a solar car from the Japanese Tokai University. The Tokai Challenger became the winner of the 2009 and 2011 World Solar Challenge, a race for solar cars across Australia. The car is designed and tested in collaboration with students and with the help of professor Licas Lofaso from Tokai University and several Japanese companies in the automotive industry. The Tokai Challenger covered the 2,998 km (1,858 mi.) off in 29 hours 49 minutes and it took an average speed of 100.54 km/h (62 mph). The Tokai Challenger also became a winner of the 2010 South African Solar Challenge recognized by the International Solarcar Federation (ISF) and the Fédération Internationale de l'Automobile (FIA), a race for solar cars across South Africa. It covered the 4061.8 km (2517 mi.) off in 45 hours 5 minutes and it took an average speed of 90.1 km/h (55 mph).

Worked examples

Example 1 — a first encounter with Tokai Challenger

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

In research: Tokai Challenger appears in astronomy 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 Tokai Challenger 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: Tokai Challenger is common in secondary-school and first-year university syllabi. It links to neighbouring topics Solar car racing, so understanding it makes those chapters shorter.
In everyday life: Look for Tokai Challenger 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.
