Q5) A material is subjected to two mutually perpendicular linear strains together with a shear strain. Given that this system produces principal strains of 1x 104 compressive and 3x 104 tensile and that one of the linear strains is 2.5x 104 tensile, determine the magnitudes of the other linear strain and the shear strain by using Mohr's strain circle. Also, find the values of the principal stresses present in the material by using Mohr's stress circle. For the material, take E=208GN/m² and v=0.3
