The strains of prismatic beam made of extruded polycarbonate were measured using multiple strain gauges. When loaded at room temperature, normal strains are 200us and 100us, while the shear strain is 45us. The modulus of elasticity is 2.38GPa, the mass density is 1200kg/m3 , the glass transition temperature is 147°C, and the shear modulus is 0.96GPa. Determine all six independent components of the stress tensor. Clearly list all your assumptions.
