The Wilmington is a town located in the Middlesex province in the Massachusetts stare in the United States. This town was initially settled in the year 1665 and it was incorporated in an official manner in the year 1730, from the regions of Billerica, Reading and Woburn. This is the place where a Baldwin apple was invented. This town is also caters as a home for the Col. Joshua Hranden Traven that potentially catered as a halt on the subterranean rail-board and at present dwelling this town Museum.
Wilmington covers an area of about 17.2 square miles, of that 0.1 square mile is covered by the water bodies and 17.1 square miles is covered by land. These town boundaries the town of Tewksbury, Billerica, Burlington, Woburn, Reading, North Reading and Andover.
Much of this town was erected on yet in wetlands. The Shawsheen River makes part of this town boundary with Billerica and Ipswich River begins in this town. You can find only 1 lake in the town called as Silver Lake, a Kettle lake assembled in the retreat of a Pleistocene glacier at an edge of a last ice age. It is free for swimming at the time of summer.
This town posses an accessible Town meeting, and it includes a town manager and a board of selectman. At present the manager of the town is Jeffrey Hull. 5 of the town’s 6 territories are depicted in the Massachusetts House of Representatives by the James R. Miceli; the previous is depicted by the Ken Gordon. The Wilmington state senator is the Bruce Tarr. The town in the Massachusetts 6th Congressional territory and is depicted in the U.S House of Representative by the Seth Moulton.
This town incorporates its own schools. Nursery school students attend the Boutwell Street and Wildwood Street schools. The Grades 1 to 3 attend the Shawsheen and Woburn Street School. The Grades of 4th and 5th attend the West Intermediate and North Intermediate School. The grades from 6th to 8th attend the Wilmington Middle School and the student of the high school attends the Wilmington High School.
The Wilmington High’s charm is the wildcat and also its athletic team competes in a Middlesex League. The Wildcat’s colors are white, Columbia blue and navy blue and the initial rivals are the Tewksbury Redman of a Merrimack Valley Meeting.
Small angles, T-bars, and channels have been used to a greater extent in Europe than in this country. They are principally used where riveted skeleton work is prepared for the steel reinforcement; and in this case, usually, it is desirable to have the steel work self-supporting. There are many forms of reinforcing materials on the market, differing from one another in the manner of forming the irregular projections on their surface. The object of all these special forms of bars is to furnish a bond with the concrete, independent of adhesion. This bond formed between the deformed bar and the concrete, is usually called a mechanical bond. The twisted bar was one of the first steel bars shaped to give a mechanical bond with concrete. This type of bar is a commercial square bar twisted while cold. There are two objects in twisting the bar—first, to give the metal a mechanical bond with the concrete; second, to increase the elastic limit and ultimate strength of the bar. In twisting the bars, usually one complete turn is given the bar in eight or nine diameters of the bar, with the result that the elastic limit of the bar is increased from 40 to 50 percent, and the ultimate strength is increased from 25 to 35 percent. These bars can readily be bought already twisted; or, if it is desired, square bars may be bought and twisted on the site of the work. The Thacher bar was patented by Mr. Edwin Thacher, M. Am. Soc. C. E. These bars are rolled from medium steel, and range in size from inch to 2 inches. The cross-sectional area is practically uniform throughout, and all changes in shape of section are made by gradual curves.
The Johnson or corrugated bar with corrugations on all four sides, was invented by Mr. A. L. Johnson, M. Am. Soc. C. E. The corrugations are so placed that the cross-sectional area is the same at all points. The angles of the sides of these corrugations or square shoulders, vary from the axis of the bars not exceeding the angle of friction between the bar and concrete. These bars are usually rolled from high-carbon steel having an elastic limit of 55,000 to 65,000 pounds per square inch and an ultimate strength of about 100,000 pounds per square inch. They are also rolled from any desired quality of steel. In size they range from - inch to ½ inches, their sectional area being the same as that of commercial square bars of the same size. The Diamond bar was devised by Mr. William Mueser. This bar has a uniform, cross-section throughout its length, exerts a uniform bonding strength at every section, and every portion is available for tensile strength. In design, this bar consists of a round bar with interlacing longitudinal semicircular ribs, and without any sharp angles. The Diamond bar is one of the newer types of bars. The Kahn bar was invented by Mr. Julius Kahn; Assoc. M. Am. Soc. C. E This bar is designed with the assumption that the shear members should be rigidly connected to the horizontal members. The bar is rolled with a cross-section as shown in the figure.
The thin edges are cut and turned up, and form the shear members. These bars are manufactured in several sizes. The Twisted Lug bar is similar in form to the Ransom cold-twisted bar, with the addition of lugs or truncated cones placed at regular intervals along the spirals. These bars are rolled with the lugs, and the twisting is done either while the bars are hot or at any time after they are cold. If the bars are twisted while hot, their elastic limit and ultimate strength are not raised; that is, their physical properties are not changed. Expanded metal is made from plain sheets of steel, slit in regular lines and opened into meshes of any desired size or section of strand. It is commercially designated by giving the gauge of the steel and the amount of displacement between the junctions of the meshes. The most common manufactured sizes are as follows: Steel wire fabric reinforcement consists of a netting of heavy and light wires, usually with rectangular meshes. The heavy wires carry the load, and the light ones are used to space the heavier ones. There are many forms of wire fabric on the market. A horizontal course of stone extending around one or more faces of a building; it is usually composed of larger stones which sometimes project slightly, and is usually employed only for architectural effect. Bonding is a system of arranging the stones so that they are mutually tied together by the overlapping of joints. Bush hammering is A method of finishing by which the surface of the stone, after being roughly dressed to a surface which is nearly plane, is smoothed still more with a bush-hammer.
