Salem covers an area of about 25.9 square miles, of that 1.2 square miles is covered by the water body and 24.7 square miles is covered by the land. This town is drained by Policy Brook and Spicket River. The greatest point in this town is the top of Gordon’s Hill that is at the height of about 380 feet above the sea level along with the Salem western border.

It is the initial New Hampshire town detected when traveling northern part from Massachusetts on the Interstate 93. Interstate’s initial 2 New Hampshire exits are located within the Salem town. Through Interstate 93, Boston is situated 35 miles towards the south and the Manchester is located 20 miles towards northwest.

Although
it would be difficult to develop any rule for the proper spacing between bars
without making assumptions which are perhaps doubtful, the following empirical
rule is frequently adopted by designers: The spacing between bars, center to
center, should be two and a-quarter times the diameter of the bars. Fire
insurance and municipal specifications usually require that there shall be two
inches clear outside of the steel. This means that the concrete beam shall be
four inches wider than the net width from out to out of the extreme bars. The
data given in Table XVIII will therefore be found very convenient, since, when
it is desired to use a certain number of bars of given size, a glance at the
table will show immediately whether it is possible to space them in one row;
and, if this is not possible, the necessary arrangement can be very readily
designed. For example, assume that six 1-inch bars are to be used in a concrete
beam. The table shows immediately that the required width of the concrete beam
(following the rule) will be 14.72 inches; but if, for any reason, a concrete
beam 11 inches wide is considered preferable, the table shows that four i-inch bars may be placed side by side, leaving two bars to
be placed in an upper row.

Following the same rule regarding the spacing of the
bars in vertical rows, the distance from center to center of the two rows
should be 2.25 >< .875 = 1.97 inches, showing that the rows should be,
say, two inches apart center to center. It should also be noted that the plane
of the center of gravity of this steel is at two-fifths of the distance between
the bars. Assume that a 5-inch concrete slab is supporting a load on concrete
beams spaced 8 feet apart, the concrete beams haying a span of 20 feet. Assume
that the moment of the concrete beam has been computed as 900,000 inch-pounds.
What will be the dimensions of the concrete beam if the concrete is not to have
a compression greater than 500 pounds per square inch and the tension of the
steel is not to be greater than 16,000 pounds per square inch? There is an
indefinite number of solutions to this problem. There are several terms in
Equation 35 which are mutually dependent; it is therefore impracticable to
obtain directly the depth of the concrete beam on the basis of assuming the
other quantities; therefore it is only possible to assume figures which
experience shows will give approximately accurate results, and then test these
figures to see whether all the conditions are satisfied. Within limitations, we
may assume the amount of steel to be used, and determine the depth of concrete
beam which will satisfy the other conditions together with that of the assumed
area of steel. For example, we shall assume that six 1-inch square bars having
an area of 4.59 square inches will be a suitable reinforcement for this concrete
beam. We shall also assume as a trial figure that x = 1.5.

Substituting these
values in the second formula of Equation 35, we may write the second formula: 900,000 4.59
X 16,000 (d-1.5). Solving for d, we find that d = 13.75. If we test this value
by means of Equation 36, we shall find that, substituting the values of I, c,
r, and s in Equation 36, the resulting value of d equals 18.33. This shows that
if we make the depth of the concrete beam only 13.75, the neutral axis will
probably be within the concrete slab, and the problem comes under Case 3, to
which we must apply Equation 29. Dividing the area of the steel, 4.50, by (b' X
d), we have the value of p equals .00348. Interpolating with this value of p in
Table XV, we find that when r = 12, k = 2.50; lcd =
3.44; x = 1.15; and d - x = 12.6. Substituting these values in Equation 29, we
find that the moment 900,000 = 2,082c, or that c = 432 pounds per square inch.
This shows that the unit-compression of the concrete is safely within the
required figure.**
