A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.
A freehub is a type of bicycle hub that incorporates a ratcheting mechanism. A set of sprockets (called a " cassette ") is mounted onto a splined shaft of the freehub to engage the chain . The ratcheting mechanism is a part of the hub, in contrast to a freewheel , an older technology, which contains both the sprockets and a ratcheting mechanism ...
A household electric fan A large cylindrical fan. A fan is a powered machine that creates airflow. A fan consists of rotating vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner.
In 2021, BYD also introduced BYD OS alongside the e-Platform 3.0, which is an in-house operating system for battery electric vehicles that decouples software and hardware. This approach reduces manufacturing and maintenance costs while offering the possibility for other manufacturers using the platform to integrate their own software and hardware.
Freefall – In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it. An object in the technical sense of the term "free fall" may not necessarily be falling ...
As of December 2024 Windows 10 is the most used versions of Windows, accounting for 62.7% of the worldwide market share, nearly double that of its successor Windows 11 at 34.11%.

There are two approaches to Gibson assembly. A one-step method and a two-step method. Both methods can be performed in a single reaction vessel. The Gibson assembly 1-step method allows for the assembly of up to 5 different fragments using a single step isothermal process. In this method, fragments and a master mix of enzymes are combined and ...
The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy.As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant, or faint for the Hubble Space Telescope. [9]
