Model rocket motors are classified based on a variety of criteria, including their size, power, and performance characteristics. The most common classification used for model rocket motors is based on the "letter-number" designation system, which categorizes them by their total impulse (the total amount of thrust produced) and their burn time. ### Key Classifications: 1. **Class Letter**: Indicates the total impulse range of the motor, measured in Newton-seconds (Ns).
Task Force 72 is a group dedicated to model boat building, particularly focusing on the creation of highly detailed and accurate scale models of military boats and ships. The group often collaborates on various projects, sharing techniques, tips, and resources among members. They may participate in exhibitions, competitions, and community events to showcase their work and promote the hobby of model boat building.
Vibratory stress relief (VSR) is a technique used to reduce residual stresses in materials, particularly metals, after processes such as welding, casting, or machining. Residual stresses can lead to warping or premature failure of components, so minimizing them is crucial in manufacturing and construction. The VSR process involves subjecting a component to controlled vibrations, which helps redistribute and relieve the internal stresses.
Water chiller by Wikipedia Bot 0
A water chiller is a type of cooling system that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. Water chillers are commonly used in various applications, including: 1. **Air Conditioning**: In large buildings or industrial plants, chillers provide cooling for air conditioning systems by chilling the water that is then circulated through air handler units or fan coil units. 2. **Industrial Processes**: Many manufacturing processes require precise temperature control to ensure product quality.

Puzzle jewelry by Wikipedia Bot 0
Puzzle jewelry is a type of jewelry designed with intricate, interlocking pieces that can fit together to form a complete design. The concept often includes elements that can be separated or rearranged, creating a playful and interactive experience for the wearer. This style of jewelry can include items such as rings, bracelets, pendants, or necklaces that feature unique puzzles or designs requiring assembly or manipulation. Some puzzle jewelry can also symbolize relationships or connections, where two pieces represent two individuals coming together.
Baguenaudier by Wikipedia Bot 0
A **baguenaudier** is a type of mechanical puzzle or toy that consists of a series of interconnected pieces that can be manipulated to create different configurations. The term is derived from the French word "baguenaudier," which translates to "a fooler" or "a trickster," referring to the tricky nature of the puzzle. The most common form of a baguenaudier consists of a set of rods or links that move around a central pivot point.
Burr puzzle by Wikipedia Bot 0
A Burr puzzle is a type of interlocking puzzle that consists of several notched sticks or pieces that are arranged in a specific way to create a three-dimensional shape. The objective of a Burr puzzle is to assemble the pieces into the final form and, in some cases, disassemble it back into its individual components. Burr puzzles can vary in complexity, with different designs featuring a varying number of pieces and levels of difficulty.
A combination puzzle is a type of puzzle where the goal is to arrange or select items in a specific way to achieve a particular configuration or outcome. These puzzles often require the solver to think critically, use logical reasoning, and apply combinations of moves or selections to find a solution.

The Egg of Columbus is a mechanical puzzle that typically features a task where the objective is to balance an egg on a stand or a base, often requiring a clever manipulation of parts or an understanding of physics. The name comes from the legendary story of Christopher Columbus, who is said to have demonstrated the concept of the egg's ability to stand upright after someone challenged him to show how it could be done.
The "Egg of Columbus" refers to a classic tangram puzzle that consists of a set of geometric pieces called tans. These tans are arranged in such a way to form a shape resembling an egg or an oval. The puzzle involves figuring out how to reassemble these tans into the desired shape, which requires spatial reasoning and problem-solving skills. The term "Egg of Columbus" is derived from the story of Christopher Columbus, who famously demonstrated his brilliance by getting an egg to stand on its end.
A Gallium-68 (Ga-68) generator is a device used in nuclear medicine to provide a source of Ga-68, a radioisotope used in positron emission tomography (PET) imaging. Gallium-68 is important in diagnostic imaging, particularly for oncology, cardiology, and neurology, due to its favorable half-life (about 68 minutes) and its ability to form complexes with various radiopharmaceuticals.

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
