- An engineer is making determinations on the best alloy of steel to use in cables for a cable-stayed bridge. The investigator’s tool is a tensile testing instrument which can measure the strength of the alloys by slowly increasing the load on the cable to the point where the cable breaks and breaking point value (amount of weight on the cable when it fails) can be accurately measured. The investigator also is interested in determining the amount of deformation of the cable (how much it stretches under load conditions which is also very important in structural considerations. The tests must be uniform and consistent to give the precision needed to make valid conclusions about the best alloy for the cables.
