4.36 A body experiences deformation characterized by the mapping where A, B, and C are constants. The Cauchy stress tensor components at certain point of the body are given by where sigma_{0} is a constant. Determine the Cauchy stress vector t and the first Piola- Kirchhoff stress vector T on a plane whose normal in the current configuration is hat n = hat e 2
