A metal hose is a flexible conduit typically made from stainless steel, although other metals can also be used. It consists of a series of interlocking metal strips or a woven metal construction that allows flexibility and movement. Metal hoses are designed to withstand a range of temperatures, pressures, and corrosive environments, making them suitable for various industrial applications.
The Ortman key, also known as the Ortman card or Ortman key card, is a structure used in geographical analysis, particularly in the field of cartography and mapping. It typically refers to a classification system of geographic features, which may include a wide range of landforms, water bodies, vegetation types, and human-made structures. The Ortman key is often employed in environmental studies and ecology to help researchers categorize and identify different types of ecosystems or landscape features based on specific criteria.
Particle damping is a technique used for vibration and shock attenuation in various engineering applications. Unlike traditional damping methods that rely on materials with viscoelastic properties or mechanical devices like springs and dampers, particle damping employs discrete particles that move within a container or a structure to absorb and dissipate energy. ### Key Characteristics of Particle Damping: 1. **Mechanism**: The basic principle involves using loose particles (often granular materials) contained within a structure.
Permissible Stress Design (PSD), also known as Allowable Stress Design (ASD), is a method used in structural engineering to ensure that a structure can safely support the loads and forces it will encounter during its life. The underlying principle of PSD is to limit the stresses in materials to safe levels, which are determined based on material properties, safety factors, and design codes.
Power engineering is a specialized field of electrical engineering that focuses on the generation, transmission, distribution, and utilization of electrical energy. It encompasses various aspects of electrical systems and technologies, including: 1. **Generation**: Involves the process of producing electrical energy, which can be achieved through various methods such as fossil fuels, nuclear power, renewable sources (solar, wind, hydroelectric, and geothermal), and more.
Range of motion (ROM) refers to the extent of movement possible at a joint, typically measured in degrees of angle. It indicates how far a joint can be moved in a particular direction, and it encompasses both active movement (initiated by muscle contraction) and passive movement (involuntary movement, such as when a joint is moved by an external force).
In the context of air conditioning and heating systems, a "register" is a grille or vent that allows conditioned air (either heated or cooled) to enter a room. Registers are typically located in the walls, ceilings, or floors of a space and are part of the distribution system for a heating, ventilation, and air conditioning (HVAC) system.
A repair kit is a collection of tools, parts, and materials designed specifically to fix, maintain, or restore a particular item or system. Repair kits can vary widely depending on their intended use, but they generally include the following components: 1. **Tools:** Basic hand tools like screwdrivers, pliers, wrenches, or specialized tools needed for the repair process.
Structural load refers to the forces and weights that a structure, such as a building, bridge, or other construction, must support and withstand throughout its lifetime. These loads are critical considerations in the design and analysis of structures to ensure safety, stability, and functionality.
"Swivel" can refer to a few different concepts depending on the context, including: 1. **Rotational Mechanism**: In a general sense, a swivel is a device or mechanism that allows for rotation around an axis. This can be found in various applications, such as furniture, camera mounts, and even in machinery.
The term "2020s software" generally refers to software that has been developed, released, or gained prominence in the 2020s decade. This includes a variety of trends and technologies that have emerged or evolved during this period. Some of the key characteristics and notable software trends from the 2020s include: 1. **Cloud Computing**: Cloud-based solutions have continued to dominate, with services like AWS, Microsoft Azure, and Google Cloud providing scalable infrastructures.
Video games that use figurines typically fall within the category of "toys-to-life" games, where physical figurines interact with the digital game world. Some notable examples include: 1. **Skylanders Series**: One of the pioneers in this genre, Skylanders allows players to bring physical figurines into the game by placing them on a special portal. Each character has unique abilities and attributes.
Run-out refers to the deviation of a rotating component from its ideal rotational path or alignment during operation, often measured in terms of how much it wobbles or deviates from a true circle. It is commonly used in mechanical engineering and manufacturing contexts, particularly in relation to components like shafts, discs, or gears.
Thermal engineering is a branch of engineering that focuses on the principles of thermodynamics, heat transfer, and energy conversion. It encompasses the study and application of heat and energy in systems and processes to design, analyze, and optimize thermal systems. Some of the key areas within thermal engineering include: 1. **Thermodynamics**: The study of energy, its transformations, and the laws governing these processes.
The Timken OK Load is a measure used to determine the maximum load that a lubricant can withstand before it fails under conditions of extreme pressure. More specifically, it is indicative of the performance of a lubricant in preventing wear and scuffing in heavily loaded conditions. The OK Load is determined through a standardized testing method, often using a four-ball tester, where a lubricant is subjected to increasing loads until the point of failure is identified.
"Treadle" can refer to a couple of different contexts, primarily in relation to sewing machines and certain types of machinery or furniture. Here are the main definitions: 1. **Sewing Machines**: A treadle sewing machine is one that is operated by a foot pedal (the treadle) rather than being powered by electricity. Users can control the sewing speed by pressing the treadle with their foot.
A turboexpander is a type of mechanical device that converts the energy in a high-pressure gas into mechanical energy by expanding the gas through a rotating turbine. The process is commonly used in various industrial applications, such as natural gas processing, refrigeration, and power generation. ### Key Components: 1. **Turbine**: The main rotating element, which extracts energy from the gas flow.
In the context of turning, particularly in machining and metalworking, an "undercut" refers to a feature or geometry that is removed from a material to create a recessed area that is not accessible with the standard cutting tools when machining the outer surfaces of the workpiece. When turning a cylindrical workpiece on a lathe, an undercut might be a groove or a notch that goes beneath the surface of the surrounding material.
Radiofrequency (RF) technology has a wide range of medical applications, primarily due to its ability to transmit energy and information safely and effectively. Here are some key medical applications of RF: 1. **RF Ablation**: This technique is used to destroy abnormal tissues, such as tumors or arrhythmogenic foci, by heating them with RF energy. It's commonly used in the treatment of certain types of cancer as well as cardiac arrhythmias.
A "monitor unit" (MU) is a measurement used primarily in the field of radiation therapy, particularly in the context of delivering a radiation dose to a patient. It represents a unit of measure for the output of a radiation therapy machine, such as a linear accelerator (linac). Monitor units are used to quantify the amount of radiation that is delivered to a specific area during treatment.
