Document Content and Description Below

GAE 11: Creatures from the past Group # Name Studies on Wrangel Island. Several different tissues have been thawed for you to examine. 1. The first one is white and quite hard. You cut a 1 cm cube w... ith a diamond saw and place it in your FORCE-O-METER where you apply a compressive force and record how the cube shrinks. You store the data in excel where you do your analysis. What do you get for the elastic modulus for this material? Any ideas as to what it might be? White cube 12100 MPa Possible material Ivory 2. Next you decide to examine some of the large brown flat tissue. You cut a small piece 1 cm wide which is 1 mm thick. You put the stretch attachment on your FORCE-O-METER so you can pull on this material generating tension. You put the data into excel. In plotting the data, you see that there are two different slopes and so decide to calculate the elastic modulus for each region separately. Brown flat tissue [Show More]
