Examples of common sizes are 2×4 (also two-by-four and other variants), 2×6, and 4×4. The length of a board is usually specified separately from the width and depth. It is thus possible to find 2×4s that are four, eight, or twelve feet in length. In the United States the standard lengths of lumber are 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24 feet.
Outside North America sizes of timber vary slightly. Sizes are, in some cases, based on the imperial measurement and referred to as such; in other cases the sizes are too far removed from the imperial size to be referred to by imperial measurement. Lengths can be sold at every 300 mm (a metric approximation of 1'). Common sizes are similar to the North American equivalent; 2.4, 2.7, 3.0, 3.6, 4.2, 4.8, 5.4, 6.0. But also in running lengths, where each plank in a given packet is different, from 2500mm to 5500mm, though shorter and longer may be present.
In North America sizes for dimensional lumber made from hardwoods varies from the sizes for softwoods. Boards are usually supplied in random widths and lengths of a specified thickness, and sold by the board-foot (144 cubic inches).
Engineered lumber is lumber created by a manufacturer and designed for a certain structural purpose.
El Puerto de Santa María
El Puerto de Santa María (commonly called El Puerto) is a city on the banks of the Guadalete River in the province of Cádiz, Spain. As of the 2005 census, the city has 82,306 people. 50,000 of these people live in the urban center. The others live in the area around the urban center.
The city of El Puerto de Santa Maria is northeast of Cadiz across the Bay of Cadiz. It is best known for its ferry, El Vaporcito, which has been used for 76 years. It takes passengers to and from Cadiz to El Puerto.
In the Odyssey of Homer, legend says that, after the Trojan War, a Greek official named Menestheus escaped with his troops through the Straits of Gibraltar. They got to the Guadalete River and created a port. They called the port "Menestheus's port".
In 711, Arab (Moors) from the North of Africa invaded southern Spain. They changed the name to "Alcante" or "Alcanatif". The name means Port of Salt. They chose that name because of the old salt industry of Phoenicians and Romans.
In 1260, Alfonso X of Castile took the city from the Moors. He renamed it "Santa María del Puerto".
Columbus began his second voyage to the New World from El Puerto. His pilot, Juan de la Cosa, created the first map of the world to include the coast of the New World in El Puerto in 1500. In the nineteenth century, the city became the General Headquarters for the French Army during the Spanish War of Independence under the reign of Joseph Bonaparte (1808–1813). The city is has much history, museums and monuments. It is also near the very historical cities of Seville and Cádiz.
El Puerto has a famous bull ring. It dates back to 1880. The bull ring has space for 15,000 to watch. Bull fighting is still enjoyed during the Feria season, which is during the month of August, and during the Feria de la Primavera, which is in early May. This Feria is dedicated to sherry. 180,0000 half bottles of sherry get drunk in 4 days. There are several bodegas in the town centre. All of these can be visited by the public. The most famous bodega is the Osborne and Terry Bodegas. They export sherry and brandy worldwide . In the cellars in El Puerto, sherry is made using the traditional method called “solera”. This method makes the pale dry sherries to the sweet Muscatel sherry, Amontillados and the older Olorosos.
El Puerto is a very good place to taste local tapas and seafood, for which it is famous. Food is an important reason why many tourists go to El Puerto de Santa Maria. The Bay of Cadiz is famous for its fresh fish. The fish and plenty of fresh fruit and vegetables lead to very good restaurant menus. There are many different types of places to eat all in walking distance in the town centre.
Bearing (mechanical)
A bearing is a device to permit fixed direction motion between two parts, typically rotation or linear movement. Bearings may be broadly grouped by the way they work. The most common of the many types are plain bearings and rolling-element bearings.
The two main types of rolling-element bearings are ball bearings and roller bearings. In ball bearings, the rolling elements are spherical balls. In roller bearings, the rolling elements are cylindrical, taper or spherical rollers. Ball bearings are shown in the pictures.
Bush (mechanical)
A bush is a mechanical fixing between two, possibly moving, parts, or a strengthened fixing point where one mechanical assembly is attached to another.
In a car or other vehicle's suspension, bushes are used to connect the various moving arms and pivot points to the chassis and other parts of the suspension. In machines, bushes provide mechanical strength to the rotor.
Suspension (vehicle)
Suspension is the term given to the system of springs, shock absorbers and linkages. The suspension acts as an intermediate between the car and the road and solves several problems:
So a car suspension is not just a set of components for connecting wheels and body or frame, but a complex system that makes normal and comfortable movement on car driving.
Springs are elastic elements of a car suspension that work in conjunction with shock absorbers. The main functions of the springs are:
Shock absorbers, as a damping element of a modern suspension, convert vibrational energy into heat. The amount of energy absorbed depends on the mass of the car, the stiffness of the spring and the vibration frequency.
The principle of operation of dampers is based on the displacement of fluid by a piston through special holes. In various modes, fluid is displaced through openings of different diameters. Due to this, the oscillations are absorbed both during compression and during rebound. As a result, these car suspension parts provide:
Using these elements, the suspension parts are fastened together, and also the suspension is attached to the body or frame of the car. The fasteners can be either a regular bolted connection (like other types of rigid joints), or a connection using special elastic elements - rubber-metal hinges (or silent-blocks).
Suzuki method
The Suzuki method, (or Talent Education, or the Mother Tongue method, or the Suzuki movement) is a way of teaching. It teaches people to be morally better through a caring environment. It normally uses a musical instrument such as the violin or piano to do this. It can also use other musical instruments like the flute, recorder, piano, guitar, cello, viola, bass, organ, harp and voice. The Suzuki method uses the same environment that people have when they learn their mother-tongue. This means that each student sees and hears music and good moral character all of the time. Other people tell them that they will do well. The students learn one thing at a time. They learn new things when they are ready. The term "Suzuki method" is also used to mean only the Suzuki sheet music books and songs.
It was created in Japan in the mid-20th century by Dr. Shin'ichi Suzuki. He was a violinist who wanted to bring some beauty to the lives of children in his country after World War II. Dr. Suzuki saw that all children learn their own language very quickly. Even dialects which adults thought were hard to learn are spoken with ease by 5 or 6 year old children. He thought that if a person can speak their mother tongue, then they can learn to play a musical instrument. He came up with the idea that any pre-school age child could begin to play the violin.
Just as a child learns to speak before reading, Suzuki students learn by ear and generally only learn to read sheet music at a much later age.
Suzuki students will always play with a "beautiful tone and a beautiful heart".
