Using the values you calculate for e, g, and ν determine what material was tested via a tabulated source (such as that in the appendix of your strength of materials textbook). using your judgment, select an appropriate yield stress and determine at what longitudinal strain your calculated value of poisson’s ratio is no longer valid. based on your physical observations from lab 1, would you expect poisson’s ratio to increase or decrease after this point? justify your answer. also, could a digital caliper with accuracy of ±0.0005in be used in place of the strain gages to measure the thickness of the cross-section? explain.

Time (minutes) amount of water (gallons) practice 1. jin fills up a 510-gallon pool in the backyard for her children. she fills it with the garden hose at a rate of 17 gallons per minute. after it is filled, she lets it sit for 30 minutes in order to let the water temperature rise. the children then get in and have fun for an hour. the pool loses about 5 gallon of water each minute due to their splashing and playing. at the end of the hour, they tear the pool while getting out, which causes a leak the pool then begins to lose water at a rate of 2 gallons per minute. a. complete the table to show the amount of water in the pool after each minute. b. create a graph to model the problem situation. include when the pool will be empty. c. write a piecewise function that models this problem situation. explain your reasoning for each piece of the function. d. identify the x- and y-intercept. explain what they mean in terms of the problem situation, atamantha a cul 80 100 120 150 200 ning, inc
