Locks are channels controlled by gates used to direct water for water control, material processing, and power generation. They can be natural or man-made and require maintenance. Locks are used to prevent flooding, retain and redirect water, and power devices like water wheels. They were also used in gold mining and timber transportation. A lock […]
Lock washers prevent threaded connections from loosening due to vibration, temperature cycling, and wear. They come in different types and sizes, such as split lock washers, star lock washers, and tabbed lock washers. They resist force through friction and can create a mechanical gripping force. They are extensively used in aircraft manufacturing and structural applications […]
Air locks in liquid piping systems obstruct flow and can be resolved by changing pressure or opening a valve. Recurring air locks may indicate a system problem. Fermentation vats require air chambers to release gas without releasing liquid. An air lock is an air bubble in a liquid piping system that creates an obstruction, slowing […]
Software hang can cause a significant decrease in computer performance and prevent further processor capacity from being used. It occurs when multiple processors attempt to modify a single data source, leading to corruption. Specialized operating system software can minimize software blocking by distributing data to processors in smaller pieces, ensuring each processing unit always has […]
The scroll lock key was once useful for programming, but is now mostly obsolete due to navigation scrollbars. Other function keys like num lock and SysRq have also become outdated.

Lock joints are a simple way to join two perpendicular pieces of wood, often used in drawer construction. A special router bit is used to cut grooves in each piece, providing good tensile strength. They are easier to create than dovetail joints, but may be less aesthetically pleasing. A lock joint is a way that […]
Locking pliers securely hold objects without needing a human grip. Different styles are available for various applications, with Vise-Grip being a popular brand. They can act like a second pair of hands and be used to loosen stubborn bolts. Quality varies, with routine maintenance recommended for longevity. Locking pliers are pliers designed to be locked, […]
Locking screws are adjustable fasteners with a threaded barrel and countersunk head. They are used for fine adjustments to a clamp’s tension and to hold a part in place or regulate flow rate. Clips and washers are used to prevent direct contact with vulnerable surfaces. Hose clamp screws tighten hoses to restrict flow, and set […]
Gimbal lock can occur in devices that move in multiple directions, such as gyroscopes. Gyroscopes aid in navigation and maintain a horizontal orientation, but can experience gimbal lock. This can also occur in telescopes and radar antennas. Pilots performing stunts manually lock the gyro instruments to avoid gimbal lock. In space navigation, gyroscopes maintain a […]
Cylinder locks can be easily rekeyed and offer quick access to the cylinder for necessary changes. They can also be recoded without replacing the locking mechanism and can be keyed to work with a common key or different keys for each lock. Cylinder locks are a common form of lock that can be rekeyed with […]
