The ambassador bridge is a suspension bridge. How does the engineering and the principles of this type of bridge relate to the study of forces?

    A suspension bridge is where the road surface is hung from some cables. The cables are held up by two towers towards the ends of the bridge.

    How does this relate to the study of forces?
    In order to build the bridge you need to know:
    How strong the cable that the bridge is hanging from must be.
    How strong the towers holding the cable must be.
    How much the cable will dip in the middle of the bridge.
    How much load you can put at any given point on the bridge.

    All of these things can be calculated by studying the forces acting on different parts of the bridge.
