Why is a 2×4 not 2×4?
A 2×4 is not actually 2 inches by 4 inches in size, but rather refers to the classification of the lumber according to certain nominal measurements. In actuality, most 2x4s measure approximately 1 ½ inches by 3 ½ inches.
The discrepancy between the nominal measurements and actual measurements is caused by shrinkage that occurs as the lumber dries out from the sawing process. Additionally, the nominal measurements take into account the roughness of the lumber before it is planed down to a smooth finish.
This necessary but slight discrepancy between actual and nominal measurements is why a 2×4 is not actually 2×4.
What type of wood is a 2×4 stud?
A 2×4 stud is typically made from softwood, such as pine or spruce. The most common type of softwood used is spruce-pine-fir (SPF). SPF is composed of mostly spruce, and a smaller percentage of pine and fir.
This type of wood is desirable when building and framing studs because it is light, strong, and relatively straight-grained. As the name suggests, a 2×4 stud measures 2 inches by 4 inches, which is the standard dimension used when framing walls.
Softwoods are not as strong as hardwoods, but they are more affordable and easier to work with.
Is poplar a hardwood or softwood?
Poplar is classified as a hardwood. Hardwoods are typically deciduous trees that have broad leaves, produce a fruit or nut, and have a lighter colored, finer grained wood. Poplar is an example of a hardwood and is commonly used for veneers, furniture, trim, and other decorative wood products.
Poplar is a light-colored wood, usually with a yellowish shade. It is a medium density wood that is fairly easy to work with and machines nicely. It is also resistant to warping and cracking. It is not a good choice for flooring, however, due to its low resistance to wear and tear.
What size is a 4×4 post?
A 4×4 post typically measures 3 ½ to 4 inches (or 8.9 to 10.2 cm) square. It usually ranges from 8 to 12 feet (or 2.4 to 3.6 m) in length, depending on the size and style of the post. The 4×4 posts are commonly used for deck supports, railing posts, landscaping, and for other structural purposes.
The posts are typically made from pressure-treated lumber, cedar, or redwood, which provides the post with resistance from rot, decay, and insect damage. 4×4 posts are available in several lengths, with the typical height set at 8 or 10 feet.
They can also be cut to shorter lengths or laminated to create longer posts. It is important to use the right size of nails, lag screws, carriage bolts, or lag shields when attaching the post to ensure its stability.
Is cedar a hardwood?
No, cedar is not a hardwood. Cedar is actually a softwood, which is derived from coniferous or evergreen trees. Its softness makes it easy to work with, making it a popular choice for furniture, decks, and siding.
Despite its softness, cedar is strong and durable, making it ideal for outdoor projects. Additionally, it is naturally rot-resistant and pests are generally not attracted to it, making it a great material for its purpose.
What is dimensional lumber?
Dimensional lumber is lumber that is cut to standard sizes and typically used in the construction of houses and other structures. It is usually sold in a variety of lengths, widths, thicknesses, and grades.
Dimensional lumber is one of the most common types of lumber in the world and usually comes in four varieties: softwood, hardwood, engineered wood, and plastic composite.
Softwood is typically used for framing walls, ceilings, and roofs in construction projects. It is typically sawn and available in a variety of sizes and lengths. The most common species of dimensional softwood used in construction include pine, spruce, fir, and cedar.
Hardwood is used for projects such as flooring and furniture making. It is usually sold in long thin blocks and cut lengths. Popular hardwoods used for lumber in the United States include cherry, oak, and walnut.
Engineered wood is produced by bonding together layers of wood veneer or thin sheets using adhesives. The most popular varieties of engineered wood include plywood, particleboard, laminate, and oriented strand board.
Plastic composites are an increasingly popular choice for outdoor projects such as decks and fences. These materials are usually more durable and weather-resistant than natural wood and require less maintenance.
The most common types of wood-plastic composites used in construction are polyethylene-based and polypropylene-based.
How is lumber measured?
Lumber is typically measured in linear feet, which is the length of the board in feet. Another common unit of measurement is board feet, which is the volume of a piece of lumber and is calculated by multiplying the length of the board by its width and height.
For example, a board that is 5 feet long, 12 inches wide, and 1 inch thick would have a board footage of 5 x 12 x 1 = 60 board feet.
In addition to linear feet and board feet, it is common to describe lumber as dimensional lumber, which is cut to specific proportions, typically in two-inch increments (with slight variations). For example, a 2 x 8 piece of lumber would be 2 inches thick and 8 inches wide, while a 4 x 12 piece of lumber would be 4 inches thick and 12 inches wide.
In the US, the National Institute of Standards and Technology (NIST) has established standards for the dimensions of lumber, and all dimensions must be referenced in either inches or fractions of inches.
For example, a 4 x 2 board would be 4 inches wide and 2 inches thick (or 4/4).
When buying lumber, it is important to be precise with measurements and understand what unit of measurement is being used. This way, you can ensure you are getting the correct quantity, size, and grade of wood you need for your project.
Who is the most famous electrical engineer?
The most famous electrical engineer is arguably Nikola Tesla (1856-1943). Born in the Austrian Empire and educated in Croatia, Tesla is most famous for his pioneering work on alternating current (AC) electricity and its use in power transmission.
He is also renowned for his experiments with radio, lightning, X-rays, remote control, and robotic engineering. Tesla’s achievements were credited with inspiring the modern electric power system, which revolutionized the way we live today.
He was also a brilliant inventor and is widely regarded as a genius in the field of electricity. Tesla’s ideas, unfortunately, often fell victim to the machinations of the corporate giants of his era, including Thomas Edison and George Westinghouse, who used their considerable influence to deny him official recognition and considerable financial reward.
Despite this, they could not deny his genius and his inventions have served as the foundation of the electric power industry today.
