A tilting keel provides stability to sailboats by pushing to the windward side of the boat as the wind pushes the sail in the other direction. It is often used with fin keels and foils for steering and maneuverability, but leakage through the plates connecting the keel to the hull is a risk. A tilting […]
Cinnamon rolls are sweet rolls made from yeast dough, filled with cinnamon-sugar mixture, and baked. They can be topped with caramel or cream cheese frosting and can include raisins or nuts. They take time to make but can be prepared overnight. Serve with coffee or juice. Cinnamon rolls, or cinnamon rolls, are sweet rolls made […]
An accumulation conveyor is used when goods need to queue or accumulate at a certain point. It differs from a roller conveyor as it includes sections that can be slowed down or stopped to allow goods to be collected. This is achieved through sensors and drive clutches. The roller conveyor is used when goods need […]
Regular maintenance of a lathe is essential for functionality and safety. Preventive maintenance can avoid unnecessary expenses. A checklist covering all parts of the machine should be reviewed frequently. It is important to not lose any parts, check drive belts, adjust gibs, inspect all components, and keep the machine clean. Complex repairs should be done […]
Spalted wood is colored by fungi living within the structure, giving it a unique look and increasing its value. Usable spalted wood is found in hardwoods, while softwoods are quickly destroyed by brown rot. Spalting is divided into pigmentation, white rot, and zone lines, each affecting the wood differently. The glazed wood is colored by […]
Level sensors detect fluid levels in pipes, containers, or other systems. They come in different designs and are used for specific applications. They can be simple gauges or detect changes in fluid levels and communicate them. They are used to detect dangerous levels of fluid buildup and can transmit data wirelessly. They use different mediums […]
Gear pumps use rotating gears to move liquids, creating high pressure and an airtight seal. They are used for water, oil, and thick liquids. The displacement principle creates low and high pressure areas, and there are two types of gear pumps: internal and external. A gear pump is a mechanical pump that moves liquids by […]
Anti-slip tape is an adhesive tape that increases traction on surfaces to prevent falls and slips. It is available in different colors and materials, with strong adhesives that work on various surfaces. It is sold in rolls and sheets, and can be used on stairs, walkways, and skateboards. It is helpful for landlords and individuals […]
Hydraulic cranes use an internal hydraulic system to lift heavy loads. They have an enclosed operator’s cab and a boom, with some having a telescopic boom. The engine drives a hydraulic pump, which applies pressure to oil or fluid within the system. Hydraulic cranes are rated by their lifting capacity and come in different models […]
Traffic engineering designs transportation systems for safer, efficient, and convenient travel. It manages bridges, roads, railroads, traffic lights, and uses advanced technologies to manage traffic patterns. Its history dates back to ancient empires, and it became more important in the 20th century with the advent of automobiles. Traffic flow management is a huge project, and […]
There are three types of rebar bending machines: manual, hydraulic, and electromechanical. Hand-operated hickey bars are the simplest and cheapest, while larger machines are usually electromechanical and built to customer specifications. The task at hand determines the best machine to use, with hickey bars being suitable for occasional use on smaller diameter bars and hydraulic […]
In traditional architecture, corners of buildings needed additional support, achieved with ashlar blocks. Quoins deflected and distributed weight, creating an aesthetically pleasing appearance. Modern architecture rarely uses functional ashlar, but decorative ashlars are popular for their old-world feel. They must be designed by architects with foresight and cannot be added after construction. Stucco ashlars are […]
There are five types of solvent degreasers: industrial, metallic, steam, detergent, and ultrasonic. Each is designed for specific applications and complies with EPA standards. Industrial degreasers are used in commercial establishments and factories, metallic degreasers are used for cleaning vehicles and machinery, steam degreasers use vapor to clean parts, solvent cleaners combine degreasing and cleaning, […]
Buddhism in Japan is often referred to as “funeral Buddhism” due to the dominance of Buddhist temples in the funeral industry and the perception that the religion is overly focused on death. As Buddhism loses popularity in Japan, some suggest that burial Buddhism may be responsible. Attempts have been made to reform the practice of […]

The Legend of the Golden Stool is a central part of their culture. They resisted European conquerors and were finally incorporated into the […]
Wet milling uses water to break down grains before grinding, making it easier to separate individual parts. The process is common for food components, but dry milling is used for flour or ethanol. The slurry is immersed in hot water with sulfur dioxide, ground coarsely, and separated into germ, fiber, starch, and gluten. The fiber […]
Land bridges connect otherwise separated islands or continents, allowing for the exchange of plants and animals. The Bering land bridge, which allowed humans to migrate from Asia to the Americas, is the most famous. Other land bridges include Doggerland, which connected England to mainland Europe, and those in Indonesia. The land bridge between North and […]
Sprockets are wheels with teeth that can mesh with other sprockets to create machines with varying gear ratios. Gear ratios determine the amount of mechanical power or multiplication created by two gears. Cogwheels allow machines to perform tasks beyond the singular force of people or horses, and can produce high-speed functions with low-speed input. Automotive […]
A superpower is a state with significant military power and global influence. The term was coined in 1944, when there were three superpowers: the US, the British Empire, and the Soviet Union. The collapse of the Soviet Union in 1991 left the US as the sole superpower, leading to anti-American sentiment. China is seen as […]
Fire partitions are walls or structures that delay the spread of fire and increase evacuation time. They differ from fire barriers in stability and do not extend across ceilings or floors. They are not expected to completely stop a fire and must meet specific safety requirements. Opinions differ on their effectiveness compared to fire barriers. […]
