La altura es de 169.4 metros.
Dado que las dos torres que sostienen un puente colgante tienen una separación de 240m y una altura de 110m a partir de la carretera, si el cable tensor más corto mide 10m, para determinar cuál es altura de un cable que se encuentra a 100m de distancia del centro se debe realizar los siguientes cálculos, aplicando la ecuación parabólica:
- (240)² = 4P x (110-10)
- 57600 = 4P x 100
- 57600 = 400P
- 57600/400 = P
- 144 = P
- 200 x 200 = 4 x 144 x (Altura - 100)
- 40000 = 576Altura - 57600
- 40000 + 57600 / 576 = Altura
-
169.4 metros = Altura
Por lo tanto, la altura es de 169.4 metros.
