Dead load is the constant weight of a structure, including fixtures intended to be permanent. Architects must perform calculations to ensure the structure can support itself and variable moving loads. Calculating dead load can be difficult, and adjustments made to accommodate it cause it to change. Buildings need to exceed their rated capacities to reduce […]
Armored cable is a power conductor cable covered in a metal sheath. There are three types: BX, true armored cable, and Metal Clad (MC) cable. The differences are small, but the grounding systems vary. BX has a poor grounding system, true armored cable has a better grounding system and heavier insulation, and MC cable has […]
A subfloor is an additional layer of flooring placed over floor joists, adding stability and improving the chances of the floor staying level. Plywood or concrete can be used, and it helps distribute stresses on floor joists and reduces the chance of the floor shifting over time. A subfloor is a type of construction used […]
Immersion heaters heat various fluids in industrial applications and come in three types: side mounted, flanged, and screw cap. Over-the-side immersion heaters are easy to clean and use different heating elements. Flanged immersion heaters are easy to control and support high tank pressure. Screw cap immersion heaters are compact and ideal for frost protection and […]
A pressure switch measures pressure and vacuum in various environments, including fluids and liquids. It is used to maintain and control supply pressure and downstream pressure of fluids. The device is used in various fields, including medical surgeries. The pressure-operated varistaltic pump is another device that measures pressure and vacuum and is used for the […]
Compressor filters remove contaminants from intake air, lubricating oil, and moisture in compressed air. Intake filters use cellulose, felt, or fabric, while water filters have a glass bowl and filter element with a drain tap. Oil filters keep lubrication oil free of contaminants. Regular inspection ensures compressor longevity and integrity of compressed air supply. Compressor […]
Concrete piles are used in pile foundations to ensure deep support for buildings, with two installation methods available. They can also reinforce walls and structures at risk of collapse, with engineers monitoring and testing their safety. Factors such as building size, soil type, and seismic activity can influence the decision to use a deep foundation. […]
Electric generators use electromagnetic induction to convert mechanical energy into electricity. They were first invented by Anyos Jedlik in Hungary in the 1820s and became suitable for industrial use after Nikola Tesla’s work in the 1880s. Today, generators come in all sizes and are used to power everything from bicycle lights to hydroelectric dams. The […]
Pipe fabrication produces pre-designed piping systems for various uses, including irrigation and fire protection. Chemical treatments, welding, and sealed joining methods are used to create a system suited to the customer’s intended use. Pipe bending allows for full customization, making it valuable for creating versatile and exacting piping systems. Fabrication is commonly used for large […]
Pulley systems use a string through a slotted wheel to move objects with less force and space. Fixed and movable pulleys can be combined to create compound pulleys, saving even more energy. They are used in factories, construction sites, and flagpoles. Pulley systems are simple mechanical devices that are used in a variety of settings […]
Lifting magnets are electromagnets used to pick up metal objects, ranging from credit card size to double bed size. They are used in various industries, including construction and auto wrecking. Different types of lifting magnets are available, including scrap magnets and magnetic sweepers. Safety precautions must be taken when using high-power lifting magnets. A lifting […]
Cooler bags are insulated containers used to keep temperature-sensitive products cool during transport. They are commonly used for medical food, vaccines, and pizza delivery. The insulation helps maintain hot and cold temperatures, and metal padding can transfer escaping heat back to its source. Ice packs can be added for extra cooling. Personal cooler bags are […]
Drum traps were once commonly used in plumbing systems to prevent large objects from entering the drain and to prevent gas from entering the home. They resemble a smaller version of a steel drum and have a sizable access plug at the top. Although P-traps have largely replaced drum traps, they can still be used […]
A heat lance is an industrial tool that generates temperatures up to 8000°F to cut through any material. It uses iron wire and high-purity oxygen and has various applications, including removing concrete, clearing rubble, and cutting scrap. A heat lance, also known as a flaming bar or heat lance, is an industrial tool that uses […]
A pilot hole is a small hole used as a guide for drilling, screwing or nailing. It is used to avoid slippage, cracking or splitting of the surface and to improve accuracy. It is also used as a guide in flatpack furniture. A pilot hole is a small hole created in a surface to serve […]
There are many types of farm jobs beyond agriculture, including agro-industry, agroscience, agricultural inspection, animal husbandry, and agribusiness. Specialized training and a college degree are often required for these jobs, which include working with companies that grow and sell agricultural products, improving the safety and quality of crops and animals, ensuring health and safety regulations […]
Aluminum powder is used in explosives, fireworks, electronics, paints, and metallurgy. It can produce exothermic reactions and is used in rocket fuel. It is also used in electronic applications and cosmetics. Aluminum powder is used in manufacturing many types of explosives and fireworks. It is also used in the production of some types of electronics. […]
The building envelope separates the interior from the exterior and includes walls, roofs, foundations, windows, and doors. Its functions are structural support, humidity control, temperature regulation, and air pressure control. Tight envelopes provide better control over indoor air quality, energy consumption, and reduce the likelihood of mold. Loose envelopes allow for natural air transfer but […]
Clack valves allow fluid to flow in one direction and prevent it from flowing back. They use a flapper valve that opens when the upstream pressure exceeds the cracking pressure. They are used in various industries and can be made of plastic or metal. The human body also has trip valves, such as heart valves. […]
Modular design breaks down units into smaller, manageable parts, and can be applied in various areas such as construction, manufacturing, and computer programming. It offers convenience, cost-effectiveness, and customization options. It also reduces errors and improves efficiency. Modular design is basically a method used to allow a specific type of unit to be broken down […]
