- 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. On the line after the item, identify which type of variable it represents from (a) independent variable, (b) dependent variable, (c) control variable. 1) thickness of the cable _____________ 5) length of the cable _____________ 2) testing room temperature…Answer with true (T) or false (F), corrects the wrong phrases, and gives short reason(s) for correct and corrected statements: 1- Normalized steels have better strength and toughness as compared to annealed steels. 2- Ferrous alloys are most important and widely used in comparison to any other metals. 3- Metals of BCC crystal structure are denser than metals of FCC structure. 4- Hypo-eutectoid steels fully annealed by heating to about 30°C above the upper critical temperature.X A3 5- The full martensite microstructure can be obtained by cooling the steels with any cooling rate. 6- There is a large volume expansion when martensite forms from austenite.,Determine the yield strength sy and the ultimate strength su of the A36 steel either from Materials Science class book/notes, or by researching over the internet.
