Outgassing is the release of chemicals from various substances, which can be harmful to human health and the environment. Examples include the smell of paint or new cars. Cheap building materials, such as those used in portable classrooms, can also cause health problems due to high outgassing levels. Outgassing or outgassing refers to the release […]
Cranes have been used for at least 2,000 years, with the Romans and Egyptians using them for monumental construction. Modern cranes can be simple or complex, with mobile, truck-mounted, rough-terrain, loading, stacking, gantry, floating, and tower versions available for various applications. All cranes use simple machines to reduce workload and are essential in many industries. […]
Corn can be grown using conventional cultivation, reduced tillage, polyculture, and storage methods, with crop rotations used for soil maintenance. Local conditions affect the best method, and some maize species are better suited to drought. Conventional agriculture uses chemicals to control pests and weeds, but has poor erosion and moisture control. Conservation agriculture retains most […]
Cantilever brackets are L-shaped metal brackets used to support heavy objects on a wall shelf. They can hold up to 1,000 pounds and come in various colors. They are commonly used to support shelving in garages, computer desks, and televisions. They are more expensive than typical metal wall brackets. A cantilever bracket is an L-shaped […]
Fossil fuels have positive impacts on the economy and social programs, but negative impacts on the environment and politics. Alternative energy sources are sought after to counteract these negative effects. Whether political, environmental or social, the effects of fossil fuels can be far-reaching and have a significant impact on the world’s population. Fossil fuels fuel […]
Cold welding is a bonding process that uses pressure instead of heat to combine two metals, but not all metals are suitable. It is best for objects in space due to its limitations. Cold welding has been around for thousands of years and can be performed with less force or by raising the surface temperature. […]
Pile foundations use long members of wood, steel or concrete to support structures on poor soils or heavy loads. They are driven into the ground with a pile driver or drilled and poured in place. A pile cap is placed on top to transfer weight to the subsoil. Quality beams can also be connected directly […]
Brick sizes are not standardized, vary by country, and have different standards for facing and paving bricks. Even the names used for brick sizes are not standardized. Actual and nominal sizes are used, but joint sizes vary, making nominal sizes inconsistent. It is best to ask manufacturers for dimensions and order surplus. Brick sizes are […]
Formwork is used to contain concrete for the construction of buildings and structures. It is important for strength and durability, and can range from 3 inches to 20 feet thick. Insulated formwork can reduce heating and cooling costs. After the concrete is set, it is smoothed by hand. Level formwork is important to prevent future […]
Air intakes or vents are important for engines and machinery that require fresh air. They are also used in furnaces, air conditioning systems, and plumbing to prevent blockages and ensure efficient operation. Combustion engines require a metered dose of fresh air for proper and efficient functioning. An air intake is a useful item in many […]
Road graders are large construction machines used to level uneven ground for various purposes, such as preparing highways, building and maintaining roads, and clearing snow. They have an adjustable blade that can create a flat or sloped surface. Some graders incorporate GPS technology for greater accuracy. They come in different sizes and are made by […]
Adhesive coatings, made from bitumen, are used in road construction to help asphalt layers bond together efficiently and withstand constant use. Proper preparation, filling cracks and potholes, and even application are important for success. The underlying bitumen holds the asphalt in place and minimizes the development of cracks and potholes. Adhesive coatings are thin layers […]
Material handling equipment moves goods in factories and warehouses, and includes transportation, positioning, cargo forming, and storage and retrieval equipment. It can impact productivity and profit margins. It may also include systems to track goods, such as inventory control software and barcodes. Materials handling equipment includes all the machinery and devices used to move goods […]
Drafting tables are desks used for drawing and other work that requires more space than a typical desk. They can tilt and are popular among artists, designers, and architects. They come in different styles and designs, with built-in rulers and trays, and can be paired with drafting chairs for comfort. Drafting tables, originally known in […]
CNC routers use computer programming to remove material from wood or metal in specific patterns or shapes. Different models offer a range of tool holder and changer systems for flexibility and speed. Machinists must be proficient in the software controlling the router’s movements. Different methods of protecting materials include pod-based suction or vacuum systems. Scrap […]
Blister packs are plastic packaging on cardboard paper used for pharmaceuticals and small consumer goods. They have individual compartments and allow for printing of specific information. They prevent tampering but may be difficult for some consumers to open. Other products can also be packaged in blister packs. Blister packs are a specific type of product […]
Actuator stems transfer mechanical output to the device being operated. They are made of metal, plastic, or aluminum, and their design depends on the actuator type and output torque. Actuators are powered devices used in dangerous environments and where space is limited. The drive rod is a physical link between the power output mechanism and […]
Combine harvesters are efficient agricultural equipment that harvest, thresh, and clean grain. They have interchangeable headers and can be used for various grains. They reduce the cost of harvesting and are available from high-tech to animal-powered versions. They have contributed to the industrialization of agriculture worldwide and are one of the main tools of commercial […]
Rock pickers are machines used to remove rocks from topsoil, commonly used in farmland or construction sites. They come in different sizes and capacities, with smaller models better for light use and larger models for covering large areas. To choose the right one, evaluate the situation and find the one that best meets your needs […]
Clean coal refers to making coal mining and power plants more environmentally friendly and efficient. However, carbon dioxide and harmful emissions are still released, and coal is a finite resource. Environmentalists argue that investing in renewable energy is better than investing in cleaner technology for fossil fuels. Coal can be chemically washed to remove impurities, […]
