Risks: wind and tension

One of the largest risk factors of the bridge is the tension on the side of the bridge. This sideways tension, caused by wind, might result in some sort of a curvature, seen from a top view. This phenomenon causes that one side of the bridge will be enlarged while the other side will be shortened. At the side where this tension arises, will the bridge be loaded by pressure. The side where the arch will be enlarged will the bridge feel tension. Since the beer crates are not one entirety, crates might drop out of the bridge at the enlarged side. The crates are not able to transfer tensile strength, after all.

To make sure the bridge will maintain during the record attempt, tension is added to the bridge. This additional tension will ensure that the side which might be enlarged due to the wind, gets pushed back to its original length. Hereby, no tensile strength will occur in the arch. The tension is established by a big press installation. This installation generates power and thus, tension in the arch. After this has been done, will the second tower be further constructed and takes over the roll of the press installation.

The amount of force that is needed to prevent the tensile strengths in the bridge are calculated based on some cross sectional characteristics and the tension due to wind, which were acquired from the national standards. The result is that a force of 111 kilonewton is needed, which comes down to the weight of more than two elephants!
