Static loads are slowly applied mechanical forces, while dynamic loads are rapidly applied. Static load tests determine maximum allowable loads on structures and materials’ mechanical properties. Elevators experience static loads, while dynamic loads occur when loading conditions change over time. Tensile tests determine a material’s tensile strength by subjecting it to tension until it breaks. […]
A pitot static tube measures air speed and altitude in airplanes by comparing the gauge pressure of air flowing into the tube with that flowing around it. It consists of two tubes, one for total pressure and the other for ambient pressure. The tube is mounted outside the aircraft and equipped with heating elements to […]
A static VAR compensator (SVC) is an electrical device that regulates voltage and stabilizes the grid in high voltage electricity transmission systems. It quickly returns reactive power to the source and can handle a larger power capacity than other options. A static VAR compensator (SVC) is an electrical device that is part of a flexible […]
A static caravan is a pre-fabricated home that can be used as permanent housing, temporary accommodation, or recreational lodging. They are typically equipped with kitchens, bathrooms, and electricity, and can be transported to their site of use. They are common in many countries, including the UK, Europe, the US, and Israel. They are available in […]
A static library is a collection of machine code files for easy linking to programs. It’s more flexible than a dynamic library and can be deleted if necessary. They’re often helpful for organization and are easy to create with a simple archiver. A static library is a computer archive that contains a group of related […]
Static random access memory (SRAM) is a type of computer memory used for running processes, but not for long-term storage. It is faster than dynamic random access memory (DRAM) but requires more space and is more expensive. SRAM is usually volatile and requires power to retain data, while non-volatile memory is used for storage. Static […]
Static variables are global data pieces that have only one value for all class objects. They can be restrictive because any change affects all objects, but also flexible as they ensure consistency. Good programming practice suggests minimizing their use. Small static data values are preferred over large ones. Static variables, also called global variables, are […]
Static methods are declared in a class and belong to the class, not an object. They are used in utility classes and cannot access instance variables. Inheritance with static methods can cause issues with polymorphism. An object-oriented computer programming method that is declared in a class but does not depend on any particular instance of […]
Static equilibrium occurs when the total forces acting on a stationary object add up to zero, resulting in no motion. This requires both translational and rotational equilibrium, with external forces and torques adding up to zero. Newton’s first law of motion applies, stating that an object will remain at constant velocity if the vector sum […]
A virtual world is a 3D environment provided by software that can be static or dynamic. In a dynamic world, users can create and own property, making it always fresh and constantly expanding. This concept is seen in SecondLife.com, where residents can purchase land and build homes. The popularity of virtual worlds is enormous and […]
A virtual world is a computer-generated 3D environment provided by a client or software program. It can be static or dynamic, with the latter constantly changing through user intervention. SecondLife.com is an example of a dynamic virtual world where residents can purchase land and build permanent features. Private property in a dynamic virtual world gives […]
Static pressure is the pressure of a stationary liquid or gas, with applications in aviation, construction, and fluid mechanics. It is important in aviation for measuring altitude, and in construction for designing effective ventilation systems. The placement of a static port is crucial to minimize position error in aviation. Static pressure is the pressure exerted […]
Static friction is the force that opposes the movement of two objects at rest, while kinetic friction opposes already moving objects. The coefficient of friction can be calculated and varies depending on the materials and surface roughness. Factors affecting friction include surface roughness, electrostatic attraction, and weak chemical bonds. Static friction is encountered in daily […]
Computers use RAM to store and retrieve information. There are two types: DRAM and SRAM. DRAM is cheaper but requires frequent refreshing, while SRAM is faster but more expensive and less space-efficient. Computers use random access memory (RAM) to store and retrieve information in an easily and instantly accessible way. There are two types of […]
Computers on the internet are assigned unique IP addresses by ISPs. A static IP address remains associated with a single computer, while a dynamic IP address changes from session to session. Static IP addresses are preferred for hosting websites, email servers, and remote access software. They are also useful for online gaming. However, they can […]
A static mixer is a tube-shaped device used to mix fluids, made of materials such as stainless steel, Teflon or polypropylene. It consists of a housing tube and baffles made from plastic or metal alloys. Mixing fluids need not be reactive and sometimes the process results in a simple blend or compound. There are different […]
The coefficient of static friction is a numerical value that determines the force required to initiate motion between two objects. It varies with the materials they are made of and is symbolized by the Greek letter “mu”. The lower the coefficient, the more slippery the surfaces are. When the gravitational force is greater than the […]
Static electricity occurs when dry materials rub together, causing an electric charge. Oppositely charged objects are attracted to each other, causing clothes to stick. Increasing humidity, using fabric softener or dryer sheets, and avoiding synthetic materials can prevent static electricity. Static electricity is a phenomenon caused by static electricity. When dry materials rub against each […]
Static electricity is a natural phenomenon that occurs when there is an electron imbalance on the surface of an object, creating a positive or negative charge. This charge is normally discharged when the object comes into contact with earth or a conductor, creating a spark. While usually harmless, static electricity can damage sensitive electronic components […]
A static budget remains fixed despite changes in sales volume or expenses, and helps organizations avoid overspending. Departments must maximize their use of the allocated funds, and set specific criteria for expenses. This budgeting tool can also be applied to households. A static budget is a budget that stays in place, even when changes in […]
