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…

Copper and copper alloys as specified by the Copper Development Association (CDA) and are designated as C00001 thru C99999 in the Unified Numbering System (UNS). True False An alloy steel designated as AISI 4130 WQT 700 means: chromium-molybdenum alloy steel containing .30% carbon in solution, that is through heat treated and water quenched. True False An AISI 4340 alloy steel contains .43 percent or 43 points of the element carbon in solution. True False Chemicals from which the commercially important plastic resins are derived are themselves derived from natural products that are quite plentiful; these raw materials include coal, water, limestone, sulfur, salt, and petroleum. True False There are two (2) types of polymerization; addition or linear and cross-linked or condensation. Addition polymers are thermoplastics and cross-linked polymers are thermosetting materials.
