10. A steel rectangular block, a=2.4cm wide and b=1.2cm deep, is subjected to an axial tensile load as shown in the figure. Measurements show the block to increase in length by x=7.11105m (initial length =10cm ) and to decrease the width by z=0.533105m when P is 45kN. Calculate the modulus of elasticity and Poisson's ratio for the material. (12 pnts)
