Newmarket is one of the town in Rockingham territory, New Hampshire, US. The population was around 8936 as per the 2010 census. Few occupants are employees and students at the near university of NH in Durham.

The initial settlement in city, where 5297 folks lived as per the 2010 census, is described as newmarket census designated site and is situated at junction of New Hampshire paths 152 and 102, adjoining to the river Lamprey.

**Newmarket - A Town of great traditions and history **

**History:**

Included in the year 1727, newmarket is the 6th cities granted by the Massachusetts in last year of reign of King called George. It initiated as an Exeter parish, and was granted complete city privileges by legislature during 1737. It was maybe titled for Newmarket in the Suffolk, England. The river Lamprey, running via the city, was titled by John Lamprey, the early colonist. For a while, the city was known Lampreyville. The town Newmarket was the center of New England shipping trade along with West Indies, incorporating importation of African slaves and sugar.

Starting with the initial cotton textile mill during 1823, the town manufacturing firm dominated the mill cities waterfront as well as economy with 7 textile mills saddling water power at falls. The firm has cotton shipped up from Deep South; hence its production was skeptically affected by American civil fight. It constructed several support structures, incorporating multifamily housing for staffs. The firm constructed dams upriver to develop Mendums Pond in the Barrington, Pawtuckaway Pond in the Nottingham and - during drought, the firm could release the regulated water flow from dams into lamprey to run the works. However the firm closed in the year 1929.

Adapted for contemporary residential and commercial utilizes the textile mills are these days mentioned on national register of historic locations. During 1970s, the mill catered as headquarters of Timberland firm, during the times when it developed from small work boot maker to a prominent urban style brand.

**Geography:**

As per to the US Census Bureau, the city has a around area of 37 km2 (14.2 square miles), of which 33 km2 (12.6 sq mi) is land and 4.1 km2 (1.6 sq mi) is water, consisting 11.4 percent of the city. Located beside Great Bay, the town Newmarket is drained by Lamprey River. The city’s biggest point is summit of Bald Hill, at 86 m (281 feet) above the sea level, nearby the city’s southwest corner.

Whenever
the percentage of steel is greater than the economical percentage, as is usual,
then the upper of the two formulae of Equation 29 should be used. When in
doubt, both should be tested, and that one giving the lower moment should be
used. Using p = .0075, and r = 12, we have k = .343; x = .114d; and (ci - x) = .886 ci. Then, since p
is greater than the economical value, we use the upper formula of Equation 29,
and have: M=76 bd2. What is the working moment for a concrete slab with 5-inch
thickness to the steel, the concrete having the properties described above? Calling
b = 12 inches, M 76 X 12 >< 25 = 22,800 inch-pounds, the concrete slab
having a span of 8 feet is to support a load of 150 pounds per square foot. The
concrete is to be as described above, and the percentage of steel is to be
0.75. What is the required thickness it of the steel? A strip 12 inches wide
has an area of 8 square feet, and carries a load of 1,200 pounds. The moment =
- Wi = >< 1,200 X 06=14,400 inch-pounds. For a
strip 12 inches wide, b = 12 inches, and Al = 76 X 12 X d2 & 912d2 =
14,400; d2 = 15.79; ci = 3.97 inches—or, say, 4
inches. The necessity of very frequently computing the required thickness of concrete
slabs, renders very useful a table such as is shown in Table XVI, which has
been worked out on the basis of 1:3:5 concrete, and computed by solving
Equation 23 for various thicknesses d, and for various spans L varying by
single feet. It should be noted that the loads as given are ultimate loads per
square foot, and that they therefore include the weight of the concrete slab
itself, which must be multiplied by its factor of safety, which is usually
considered as 2. For example, in the numerical case of Article 269, we computed
that there would be a total load of 700 pounds on a span of 6 feet. In the
column headed 6, we find 794 on the same line as the value of 3.0 in the column ci. This shows that 3.0 is somewhat excessive for the
value of ci. We computed its precise value to be
2.82. On the same line, we find under "Spacing of Bars," that *-inch
square bars spaced 5 inches will be sufficient. In the above more precise calculation,
we found that the bars could be spaced 6 inches apart, as was to be expected,
since the computed ultimate load is considerably less than the nearest value
found in the table. What is the ultimate load that will be carried by a 5-inch concrete
slab on a span of 10 feet, using 1:3:5 concrete? The 5 inches here represents
the total thickness, and we shall assume that the effective thickness (d) is 1
inch less. Therefore d = 4 inches. On the line opposite d = 4 in Table xvi and
under the column L = 10, we have 508, which gives the ultimate load per square
foot. A 5-inch concrete slab will weigh approximately 60 pounds per square
foot, allowing 12 pounds per square foot per inch of thickness. Using a factor
of 2, we have 120 pounds, which, subtracting from 508 leaves 388 pounds;
dividing this by 4, we have 97 pounds per square foot as the allowable working
load. Such a load is heavier than that required for residences or apartment
houses. It would do for an office building. The concrete floor of a factory is
to be loaded with a live load of 300 pounds per square foot, the concrete slab
to be supported on concrete beams spaced 8 feet apart. What must be the
thickness of the concrete floor-concrete slab? With 1,200 pounds per square
foot ultimate load for the live load alone, we notice in Table XVI, under L =
8, that 1,241 is opposite to d = 5. This shows that it would require a concrete
slab nearly 6 inches thick to support the live load alone. We shall therefore
add another half-inch as an estimated allowance for the weight of the concrete
slab; and, assuming that a 6k-inch concrete slab having a weight of 78 pounds
per square foot will do the work, we multiply 300 by 4, and 78 by 2, and have
1,356 pounds per square foot as the ultimate load to be carried.**
