A Short Glimpse Into New Castle In New Hampshire

New Castle is one of the towns in the Rockingham province of the New Hampshire State in the United States. This town is one among the smallest and located on the easternmost part in New Hampshire. New Castle is the only town situated completely on islands. This town caters as home for the Fort Stark Historic Site, Fort Constitution Historic site and the New Castle Common, is a 31 acre recreation region on the Atlantic Ocean. Along with this, it also serves as a home for the historic Wentworth by the Sea hotel and the United States Coast Guard.

Geography:

This town covers an area of about 2.4 square miles, of that 1.5 square miles is covered by the water body and 0.8 square miles is covered by the land. This town occupies an archipelago, incorporating one major island and plenty of smaller lands bounded by the Atlantic Ocean and the River Piscataqua. A greatest point of this town is situated at the Wentworth by the sea hotel, at the height of about 60 feet above the sea level.

Schools available for New Castle Residents

The New Castle is the part of School Administrative District 50. The Maude H. Trefethen School offer education for the kids from Kindergarten up to 6th grades. Afterwards children were sent to the Rye Junior High school it gives education from 7th to 8th grades. And the Portsmouth High School gives education offer Grades from 9th to 12th.

Fire suppression department found in New Castle

This station is situated in the center of this town; it houses plenty of firefighting tools. The firefighters were trained weekly on fundamentals of firefighting like fire apparatus operation, large diameter hose functions, fire ground safety, Rapid Intervention Team, Wild Land firefighting, rescuing victims from the dangerous regions’ ladder skills and fire hose movement. They try to handle a consistent level of ability in these kinds of core regions, hence, while the time comes, they will be capable to react properly as well as rapidly. In addition to this, this town Fire Departments reacts to a huge number of medical emergencies yearly.

Sites of interest in this town

This town entices number of travelers towards it, because it incorporates so many beautiful spots. Some of them are Portsmouth Harbor Light, New Castle Historical Society and Museum, Fort Stark State Historic Sire and Fort Constitution State Historic state.

We have already determined that: Substituting the above value of Ic in this equation, we have, after considerable reduction: The above equation shows that we cannot select the percentage of steel at random, since it evidently depends on the selected stresses for the steel and concrete, and also on the ratio of their module. For example, consider a high-grade concrete (1:2:4) whose modulus of elasticity is considered to be 2,900,000, and which has a limiting compressive stress of 2,700 pounds (c'), which we may consider in conjunction with the limiting stress of 55,000 pounds in the steel. The values of c, s, and r are therefore 2,700, 55,000, and 10 respectively. Substituting these values in Equation 18, we compute p = .012. What percentage of steel would be required for ordinary stone concrete, with r = 15, c =2,000, and s = 55,000 ANS 0.95 percent. The moment which resists the action of the external forces is evidently measured by the product of the distance from the center of gravity of the steel to the cancroids of compression of the concrete, times the total compression of the concrete, or, otherwise, times the tension in the steel. The compression in the concrete and the tension in the steel are equal, and it is therefore only a matter of convenience to express this product in terms of the tension in the steel. Therefore, adopting the notation already mentioned, we may write the formula: But since the computations are frequently made in terms of the dimensions of the concrete and of the percentage of the reinforcing steel, it may be more convenient to write the equation: From Equation 12 we have the total compression in the concrete. Multiplying this by the distance from the steel to the cancroids of compression (d - x), we have another equation for the moment: This equation is perfectly general, except that it depends on the assumption as to the form of the stress-strain diagram as described in Article 260. On the assumption that q = 'for ultimate stresses in the concrete, the equation becomes: When the percentage of steel used agrees with that computed from Equation 18, then Equations 20 and 22 will give identically the same results; but when the percentage of steel is selected arbitrarily, as is frequently done, then the proposed section should be tested by both equations. When the percentage of steel is larger than that required by Equation 18, the concrete will be compressed more than is intended before the steel attains its normal tension. On the other hand, a lower percentage of steel will require a higher unit-tension in the steel before the concrete attains its normal compression. When the discrepancy between the percentage of steel assumed and the true economical value is very great, the stress in the steel (or the concrete) may become dangerously high when the stress in the other element (on which the computation may have been made) is only normal.

268. Example 1. What is the ultimate resisting moment of a concrete beam made of 1:3:5 concrete, which is 7 inches wide, 10 inches deep to the reinforcement, and which uses 1.2 per cent of reinforcement? The concrete is supposed to have a ratio for the module of elasticity (r) of 15. The ultimate strength of the concrete is assumed as 2.000.

Answer. From Table XIII, p = .012, and r = 15, Ic = .490; x = .357 lcd = .175 d; d - x = .825 d. From Equation 22 we have: M0=>< 2,000 x .490 X 7 X10 x 8.25=330,137 inch-pounds. The total compression in the concrete is the continued product of all the factors except the last, and equals 40,017. But this equals the tension in the steel, whose area = pbd = .012 x 7 X 10 .84 square inch. Therefore the unit-stress in the steel would equal 40)017 ± .84 = 47,640 pounds per square inch. This is considerably less than the usual ultimate of 55,000, and shows that the percentage of steel is considerably in excess of the normal value.
