10. The central span of the Golden Gate bridge is 4200 ft long
and the towers' height from the roadway is 500 ft. The shape of
the main suspension cables can be approximately modeled by the
equation:
500 ft
f(x) = Ce/C +e=x/C
2
1) for -2100 <x<2100 ft
2100 ft
where C
4491.
By using the equation L = [°/1+[f'(x)]1² dx, determine the length of the main suspension cables with
the following integration methods:
(a) Simpson's 3/8 method. Divide the whole interval into nine subintervals.
(b) Three-point Gauss quadrature.
