Modern suspension bridges are light and aesthetically pleasing and can span longer distances than any other bridge form. They are also among the most expensive bridges to construct. Though suspension bridges can be made strong enough to support freight trains, they have nearly all been designed for automobile traffic.

The main forces in a suspension bridge are tension in the cables and compression in the towers. ... The use of suspension bridges makes longer main spans achievable than with any other types of bridges, and they are practical for spans up to around 2 km or even larger.Suspension bridges get their name from the fact that the roadway is suspended by cables from two tall towers. Most of the weight is supported by the two towers. They, in turn, pass the compression forces from the cables directly into the ground. Suspension bridges also have smaller cables called suspenders.

The towers of most suspension bridges are made of steel, although a few have been built of steel-reinforced concrete.

Answer from: Quest

the investment was $14,174.196

explanation:

a lump sum means that the father of the example made one deposit and leave it be.

we need to know the value of a capital that generated at 4.05% per year during 28 years the sum of $48,613.24

$capital * (1+0.045)^{28} = 48,613.24$

now clearing the formula to solve for capital we got:

$capital = \frac{48,613.24}{(1+0.045)^{28}}$

and we reach the answer investment = $14,174.20
