Internal frame backpacks have a lightweight frame made of plastic or aluminum, with fabric straps for support. They lack external attachments but are ideal for long hikes and rough terrain, keeping contents safe and fresh. In an effort to carry everything we need while backpacking, even if we keep the load as light as possible, […]
The drive frame is crucial in mining as it drives additional conveyor segments and keeps the system steady and secure. It must be made from strong materials, contain few bolted parts, and be compatible with the carrier system. Bushings are used to allow movement and can be replaced easily. A drive frame is an integral […]
Balloon frame is a wooden frame used in construction to build buildings. It consists of wooden studs, plywood, and rafters. The term “balloon frame” came from critics who thought it was fragile, but it allowed for rapid construction and shipping of homes across the US. It did not require skilled workers and used nails to […]
Moment frames are box-shaped frames with special joints that aid in resistance to wind and earthquake damage. There are three types: ordinary, intermediate, and special. Buildings are intended to bend with moderate momentum and return to their previous state, but to survive a major earthquake, the frame should bend and absorb energy without falling over. […]
Frame scaffolding is a common type of scaffolding used on construction sites. It is assembled by connecting two sections of scaffold frame with cross sections of support posts, and workers climb the sections to assemble the next one. Pins and stud clips secure the sections together, and aluminum deck planks provide a surface for workers […]
Chassis ground is a connection to ground on the case of an appliance or the body of a vehicle. It provides a potential-free voltage reference and dissipates interference, transient voltages, and static electricity. Grounding is important for establishing reference voltages and protecting circuit components. Automobile electrical systems are typically negative ground loops, with the chassis […]
An A-frame hoist is a portable gantry hoist that can be used in various locations. It has two stable legs with an overhead trestle and can be adjusted for different projects. It can lift a variety of objects, but weight limits should be observed. Manufacturers offer different sizes and weight classifications, and custom fabrication is […]
Space frame design is a skeleton-type approach to building construction and automotive manufacturing that offers weight savings, increased stiffness, and increased durability. The concept dates back to the 1900s and is rooted in the natural stiffness of angular constructs. Spatial structures are most commonly employed in large rooftops and experimental buildings, while some high-end automakers […]
Frame punches are tools used to punch shaped holes in sheet metal, similar to cookie cutters. There are three types: hand, ratchet, and hydraulic. The design consists of a punch, die, and screw. A hole is drilled in the sheet metal, and the punch is pulled through using the screw. The type of punch used […]
A front frame is a wooden outline used for appearance and function in cabinets. It can add stability, decoration, and a traditional look. Face frames are made by connecting posts and rails with mortise and tenon joints, and can have decorative trim. They are usually made from plywood and can accommodate various door hinges. Cabinets […]
The feather frame, developed by Norton Motorcycles, was a revolutionary motorcycle frame design that used hydraulic dampers to smooth out the ride. It outperformed competitors in a road race and is still reproduced today. The feather frame is a motorcycle frame design that was a precursor to most modern motorcycle frames. The boom frame was […]
Bezel setting is an ancient method of securing stones in jewelry with a metal band. It is safe, versatile, and protects the stone from scratches. Bezel settings can be full or partial, and are popular in modern jewelry design. Quality bezel settings should have stable stones, aligned facets, and no damage. Bezel setting is a […]
A web frame is the internal frame of a wardrobe that holds drawers and divides cabinets. It consists of a front bezel, side rails, and runners. A dovetail joint is often used for strength and nuts can support side rails in solid wood furniture. A web frame is the internal frame of a wardrobe. This […]
Choosing the best power loom depends on the weaver’s needs, budget, and desired level of automation. Production rates vary between machines, with air or water jet looms being the fastest. Size and human interaction also play a role in selecting a power loom. New machines offer custom options and maintenance/training, but used machines can be […]
Steel framing is a construction technique using steel supports to form the basic shape of a building. It provides superior strength, uniform walls, and is not susceptible to mold or rot. However, it is more expensive and requires experienced installers. Steel beams should be protected from fire. Steel framing is a construction technique that uses […]
Steel frames are an alternative to traditional wooden frames used in commercial and residential construction. Steel frames offer durability, strength, and resistance to pests and fire. Steel frames are more expensive than wood and require specialized tools and techniques, making it less popular in residential construction. A steel frame is a structural system used in […]
Relational frame theory explains how humans infer relationships between objects using language and symbolic relationships. It expands on BF Skinner’s theories of behaviorism and highlights the unique cognitive learning tool of language possessed by humans. Humans can infer relationships using imagination and experience, while non-human organisms can only identify relationships through conditioning. Relational frame theory […]
A frame grabber is an electronic device that records still images or video and can be connected to a computer. It can capture frames from video and has evolved to capture entire videos. It makes it easier to capture images or video on a computer and can be used for manipulation or enhancement. Software grabbers […]
A sampling frame is a list of eligible members of a population used to draw samples for surveys and studies. It helps researchers arrive at unbiased and accurate conclusions by defining the population studied. However, the frame may not include all members of the population of interest and may have errors that can skew results. […]
Frame relay is a fast and efficient way to transmit data packets between LANs in a WAN. It uses virtual circuits and is relatively inexpensive, but does not provide end-to-end data correction. It can deliver data with high reliability and is a valid alternative for data transmission. Frame relay is a computer network structure that […]
