Answer questions in reference to the figure below (use Specimen 2 for calculations). *Note that in this diagram strain is expressed as a percentage, in which the strain value multiplied by 100. Stress [MPa] 700 650 600 550 500 450 400 350 300 250 200 150 100 50 Specimen 1 Specimen 2 - Specimen 3 0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 Strain [%] 1. Calculate the Elastic Modulus of this alloy. 2. Estimate the tensile strength. Explain the rationale behind your estimation. 3. Use the 0.002 strain offset method to determine the yield strength of this alloy. Draw this offset on the diagram so it is clear how you are determining the value.

Peter Parker is looking for new materials for his synthetic web. Materials generally involve polymers, which are long, repeating molecules, which can be linear or branched, which can have molecular masses in the order of thousands or tens of thousands of Daltons. To prepare polymers, advanced reactions are usually required, such as coupling reactions, Ziegler – Natta, advanced oxidations, among others. The characteristics of the polymer depend of the properties of the geometry and polarity of its precursors, so Parker decides to study different precursors proposed by Tony Stark. Help Parker with his investigation: a) Stark proposes to Parker that he can use some anions as crosslinking ligands between cationic polymers to increase the strength of your webs. He proposes you to try the anions of sodium dithionite (Na2S2O4), lithium borohydride (LiBH4), calcium hexafluorophosphate (Ca (PF6)2), ammonium fluorophosphate ((NH4)2PO3F) and sodium thiosulfate (Na2S2O3). Propose the most probable…
