Plots are provided below from tensile tests carried out on 15mm wide machinemade paper of basis weight 90g/m2 and density of 800kg/m3 using a span length of 8cm. Use these data to answer the following questions. tensile strength in kNm/kg for the machine (MD) and cross (CD) directions. (20 points) Using the provided data, estimate the initial slope (in N/mm ) for a test strip of the same paper tested with the MD at a 45 angle relative to the vertical axis given that the vMDCD (major Poisson's ratio) =0.15 and GMDCD= 2.10MNm/kg
