- 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…arrow_forwardWhat is the difference of a non-ferrous alloy and steel components, for example in bicycle?

- Nickel-based alloys are used for gas turbine blades in aerospace engines. Briefly discuss the characteristics that make these alloys the choice for this application. Single-crystal technology is applied to nickel alloys that are used as gas turbine blades in aerospace engines. With the aid of sketches describe how a single-crystal casting can be manufactured and explain why a single-crystal casting is likely to have superior creep resistance than a directly-solidified one. Demonstrate the application of the Ten-percent Rule by calculating the approximate tensile strength and elastic modulus in the 0° direction of a carbon-fibre reinforced polymer composite if the strength and elastic moduluş in the 0° single ply are 3620 MPa and 143 GPa respectively. The lay-up sequence of the composite is [02/+45/-45/902]s.arrow_forwardRead the question carefully and give me right solution according to the question.
