Results obtained from a tension test on a bar ofuniform cross section 10 mm x 10 mm subjected to an axial pull of8000 N were tabulated. The lateral dimensions of the bar were foundto be changed to 9.9985 mm x 9.9985 mm while using a materialhaving modulus of rigidity equal to 0.8 x 107 N/cm2. By determiningthe values for different moduli, identify the properties ofmaterial and establish the relationship between them. What changeswill happen to the volume if the length of the bar is equal to 2.5m? Based on the results obtained discuss how the elastic constantsare related to the deformation of the bar?  Â
