deff fn [24]

Answer:

Step-by-step explanation:

Given

span of bridge L=1270\ ft

height of span h=157\ ft

Equation of Parabola

y=0.00039x^2

|x| i.e.

-635

\frac{dy}{dx}=2\times 0.00039

length of Arc=\int_{a}^{b}\sqrt{1+(\frac{dy}{dx})^2}

=\int_{-635}^{635}\sqrt{1+(\frac{dy}{dx})^2}

=\int_{-635}^{635}\sqrt{1+(0.00078x)^2}

=2\times \int_{0}^{635}\sqrt{1+(0.00078x)^2}

=2\times (660.08)

=1320.16\ ft
