A counterbalance forklift uses a large counterweight to balance the weight lifted by the forks. The weight is attached to the rear of the machine and can be filled with chloride to increase lifting capacity. Operators must know the lift capacity and estimated weight of the load to prevent tip-over conditions. Overly large counterweights can […]
Tool bits are non-rotating cutting bits for power tools like milling machines and lathes. They are made of hardened high carbon tool steel and are specially shaped to cut specific profiles. Standard profile geometry standards ensure operator safety and effective chip removal. Tool tips can be resharpened and re-profiled for different cuts. Design considerations prevent […]
Pedestrian gates are designed to control access for people, often through a narrow design that prevents vehicles from passing. They are used in various contexts, from residential courtyards to transit stations, and can include turnstiles and kissing gates. Some gates are low, while others are taller for added security or privacy. A pedestrian gate is […]
A workshop is a space for small-scale production, repair, or DIY projects. It should provide sufficient space, light, and ventilation for a safe working environment. Different types of workshops have specific layouts and equipment, but all require proper storage, lighting, and safety measures. “Workshop” is an umbrella term describing any building, room, or area dedicated […]
An electric demand meter charges customers more for peak demand periods, as electricity cannot be stored. It measures the highest level of demand over a period of time and allows the company to recoup costs while maintaining affordable prices. An electric demand meter works on the principle that customers who require a higher or more […]
Photovoltaic cells convert sunlight into electricity by using layered materials, including silicon, an anti-reflection coating, and a glass cover. Silicon is modified with elements like phosphorus and boron to create an electric current. An anti-reflection coating is necessary to increase efficiency. As technology advances, photovoltaic cells may provide free energy for homes and businesses. Photovoltaic […]
Chemical resin is a synthetic material that hardens, similar to natural resin. Types include plastic, acrylic, polypropylene, and melamine resin. Plastic is used for packaging, acrylic for hard products, polypropylene for food containers, and melamine for tableware and laminates. Chemical resin is a term used to describe synthetic resins. Natural resin is produced by most […]
Neoprene and polyethylene gaskets have different uses due to their ability to withstand different temperatures and pressures. Neoprene is used in high-temperature situations while polyethylene is used in lower temperatures and can provide a seal that can be broken and restored. Neoprene and polyethylene gaskets share many similarities, but each has its place in the […]
Polyethylene is a strong plastic made from petroleum, commonly used in items such as shopping bags and bulletproof vests. Thin sheets are sold in rolls and used in commercial and industrial businesses, as well as in construction and agriculture. Thicker sheets are used for cutting boards and signage. Environmentalists are concerned about its non-biodegradable nature, […]
A gambrel truss is a roof support with two slopes on either side of the summit, often used in barns and sheds for extra floor and headroom. It transfers weight to the walls and can be made of wood, metal, or composites. The design is resistant to severe weather but may be difficult to heat […]
Electronics engineers design and manage the quality assurance and project management of electronic products. A bachelor’s degree in electrical engineering and certification are required. They work in manufacturing, research, and product development. They design and test new products, manage projects, and work with customers, suppliers, and manufacturers. Quality assurance is required for new and existing […]
A blower assembly consists of a motor, fan, and casing and is used in various equipment. It can vary in size, shape, and how it’s secured. The fan wheel is called a squirrel cage and can be delicate. Larger equipment may have dual blower assemblies. Cleaning consists of mild soap and water. A blower assembly […]
Thermosyphoning is a process of exchanging heat without a pump, commonly used in solar water heaters. It relies on convection and can be used for soil cooling and computer cooling. Thermosyphoning, also known as thermosyphoning, is a process used to exchange heat from liquids without a pump. This eliminates costs and simplifies the heat transfer […]
Countersinks are cone-shaped holes drilled into objects to fit screw, bolt, or nail heads. They come in various styles and sizes, with bevel angles ranging from 60 to 120 degrees. Countersinks remove sharp edges and can increase strength in sheet metal applications. Special tools, such as cross hole and slotted countersink cutters, are used for […]
Lumber grading evaluates wood’s appearance or strength, with grades indicating acceptable purposes or non-defective wood percentage. Hardwoods and softwoods are graded differently, with hardwoods classified by clear surface percentage and softwoods by structural integrity or appearance. Grading standards are set by organizations, and different grades are used for different projects. Softwood size is classified based […]
Compound angles are formed by cutting wood at an angle to the horizontal and vertical plane. They are important for creating tight-fitting joints in structures such as buildings, furniture, and picture frames. Compound angle cuts can be made with power or hand-operated saws, and require careful calibration or the use of clamps, fences, and jigs. […]
Expanded polystyrene is a lightweight, buoyant, and good insulator material made by combining ethylene and benzene to create styrene. After cleaning, the pearls are expanded in three stages and can be molded into various shapes. It is more environmentally friendly than extruded polystyrene and requires less energy to produce than paper alternatives. It does not […]
Polyolefin is a non-polar, odorless, and non-porous thermoplastic polymer used in consumer goods, food packaging, and industrial products. It is created by polymerizing a simple olefin and consists of carbon and hydrogen atoms. Polyolefins are easy and cheap to dye and shape, and include polybutene, polyethylene, and polypropylene. Polyolefin is the largest class of organic […]
Exploratory drilling is used to assess soil content and identify valuable materials in various industries, such as mineral exploration and oil drilling. Core samples are taken to determine quality and quantity, and more holes may be drilled if the site is deemed profitable. Geologists can also use drilling to learn about geological strata and climate […]
A tenon is a male component of a mortise and tenon joint used to create a strong connection point. There are different types of tenons, including stub, through, tusk, and feather. Tenons are used in various fields, from furniture making to wooden frame construction and have been used for thousands of years. A tenon is […]
