For an engineering application, a plate of a titanium alloy (ti-6a1-4v) with a rectangular cross-section, and a length of 2 m will be subjected to a tensile force of 55 mn. the facture toughness of this alloy is 55 mpaym, the modulus of elasticity is 114 gpa and the yield strength is 910 mpa. a) determine the cross-sectional dimensions of the rectangular plate at the point at which yielding initiates. the ratio of the two sides of the rectangular cross-section is 1: 5. [3 marks] b) at the point at which yielding initiates, given that the deformation is entirely elastic up until this point, what will be the resultant elongation of the plate? [2 marks] c) calculate the size of an interior crack that will lead to catastrophic failure at an applied stress of 50% of its yield strength.

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
