A structural member in a nuclear reactor is made of a zirconium alloy. E = 100 GPa oy = 300 MPa. The material has elastic behavior. Part A If an axial load of 14 kN is to be supported by the member, determine its required cross-sectional area. Use a factor of safety of 3 relative to yielding Express your answer to three significant figures and include the appropriate units. HA A= 0.14 mm

I asked for problems 6 and 7 to be answered, but I did not get a properly structured answered as the example shows on problem number 1. Here is the link to the questions I already had answered, could you please rewrite the answer so its properly answered as the example shows (Problem 1)?   https://www.bartleby.com/questions-and-answers/it-vivch-print-reading-for-industry-228-class-date-name-review-activity-112-for-each-local-note-or-c/cadc3f7b-2c2f-4471-842b-5a84bf505857

I need these three parts answered, if you are unable to answer all three parts please leave it for another tutor to answer, thank you.

Posted below is a picture of a data table and a diagram of an experiment. In the experiment you rolled a marble down a ruler ramp off the end of a coffee table to observe projectiles and conservation of energy. You do 3 trials for each initial height. Each height is measured in meters. h= initial height of marble off of table Y= height of table off floor X= horizontal distance marble goes from edge of table to where it strikes the floor a) use the table to find information you need to solve for theoretical range and % of error in measured range.
